Business Case (I know how you PMs love these):
The current CB 1902 implementation is going to make this conversation part of our helpdesk script:
“What screen is the app on?”
“Can you move that window to the monitor where X is showing?”
“No, not that one.”
“Nope, still don’t’ see it”
“Ok let me reconnect in full screen, please accept the prompt again.”
“No no no, don’t hang up the phone, that’s not how this works.”
“Ok, you should see a prompt to allow me to connect.”
“Nope it’s there, trust me.”
“Got it, thanks. Ok, let me move that over here.”
“Ok, I’m going to reconnect again so I can see what’s going on.”
*Click*
“You just hung up, didn’t you?”

This is going to waste time on support calls and leave both sides dissatisfied with the entire experience. In turn, customers will continue implementing other third party remote control tools. Remove Viewer was absolutely a selling point for ConfigMgr and was one of the features that lured us away from our previous solution.

Solution:
1) The ability to select _any_ single screen connected to the remote device in addition to the current all screen view.
2) The ability to change monitor selection without having to reconnect the remove viewer.

Notes:
I could probably live with automatic reconnection provided that the admin stays in the Remote Viewer app at all times and doesn’t need to retype anything (device name/credentials) nor the end user re-accept the prompt if one is configured.
In my dreams the ability to pick a single screen is built into the full screen mode. In full screen mode the admin clicks a button that overlays each monitor with a number and an outline. If this sounds like display setting’s ‘Identify Monitors’ that’s because that’s exactly what I’m thinking of. However, don’t stop there. In that identification mode make the monitors selectable such that when I click on one it immediately becomes the single monitor I’m connected to.

TL;DR: Make Phased Deployments for Applications the same as Phased Deployments for Task Sequences where you can create up to 10 phases and manually initiate the second phase of deployment.

Explanation:
Currently in 1806 although you can create a phased deployment for an Application, you're limited in two key areas:

1) You cannot manually create phases for an application
2) You cannot manually begin the second phase of deployment for an application
3) You are limited to 2 phases for an application

In our environment we follow a controlled graceful deployment process where an Application Model application is deployed office-by-office to prevent flood of support calls should an unexpected situation arise. Since we have multiple offices across the globe, a single application may have as many as 13 deployments, although it's typically around 6.

Phased Deployments is the solution here but it's usefulness in the context of Applications is limited. If it could match features available in Task Sequence deployments it would be of significant value.

Today, when you install the CM Console, the PowerShell module will be placed under the %CMInstallDirectory%\AdminConsole\Bin\ConfigurationManager.psd1

This makes sense given where the user is choosing to install the console, and that's fine. But placing it here off the beaten path means that it is not importable using PowerShell's module autodiscovery features. For instance, if a module is found in any of the standard user or system paths (or registered under the $ENV:PsModulePath) the user can easily import the module without having to specify the full path, a big user quality of life win. This is the way that SQL Server handles their modules, and they are the golden child, beloved by all PowerShell nerdoes like me.

So, my suggestion is to continue placing it where it is today, and also register the path using the standard mechanism, excerpted below.

[Environment]::SetEnvironmentVariable("PSModulePath",$p)

Content Replication from Site to DPs should be a frustration free Process or SCCM Admins. Unfortunately, I know no customer without smaller or bigger issues in this area.
Here is an uncomplete list of some issues I´ve noticed:
• Content Eval - Scheduled Task lost
o SCCM does not check if the schedule task got lost/deleted
o Suggested Solution: SCCM should verify the Scheduled Task on Service Startup
• Content Eval - Hash mismatch/Eval fails for package
o When content Eval fails for a package, the admin must manually redistribute it / take care of the error
o There should be an option in SCCM to automatically fix packages where Content Eval fails
• Content Eval - Immediately validate content after distribution
o When an invalid package gets send to a DP, it can happen that it goes into the state "Successfully distributed content"
o However, to content is invalid. If you run a content validation immediately will go to "Could not validate…"
o Makes troubleshooting much harder, as you must verify every package before it is "really" OK
o Suggested Solution: Immediately validate content after distribution
• Content Eval - Failed to retrieve the package list on the DP
o If DP has this error, it never gets fixed automatically
o If WMI Entry is missing and .INI file is there, smsdpmon.log does not tell which package is affected
o Content Eval Task does just use package list in local WMI (SMS_PackagesInContLib), but it should verify all packages assigned to it.
o WMI/INI fix script (eg: here, but many scripts like this exist on the internet) can fix the error, but will cause other issues.
o Suggested Solution: When Content Eval runs, the DP should download a list of Packages to verify (PkgServers Table?)


• Waiting for Content - Content did not arrive from CAS
o Content available (and verified) on Primaries - however some Secondary Sites have the status "Waiting for Content from CAS”
o Workaround: Reset Status in DB for Primary and Secondary and Redistribute
• DP and Pull DP - Handle Empty Packages
o SCCM DPs cannot handle Packages without content
o Scenario 1: Deployment Packages get empty automatically, because Updates expire
o Scenario 2: Create Package with content and deploy to DPs – Remove “this package has source files” checkbox
o Content Validation on DP will fail - DP will go to warning state
o Workaround: Detect and remove empty packages
o Suggested Solution1: DPs should be able to handle empty packages
o Suggested Solution2: SCCM should detect empty packages and remove them from all DPs
• DP and Pull DP - Redistribute does not fix .INI file issues
o If Content of INI file in PkgLib is invalid, a redistribute does not fix it
o Suggested Solution: Always rewrite INI File on redistribution


• Database - PkgServers, ContentDPMap and PkgStatus not in Sync
o Content is distributed and verified successfully to DPs
o Content is not written correctly to ContentDPMap Table (can happen if status message gets lost)
o PullDPs and Clients can´t download the Package
o Workaround: Redistribute affected Package
o Suggested Solution: If Content is OK on a DP, the ContentDPMap+PkgStatus should reflect this => When Package is successfully validated on a DP, all needed Tables should get checked/updated

We are using PowerShell as a frontend for creating applications. As default we create multiple deployment type, each of them intented to run in certain environemts. These environemts are defined in some custom global conditions.

When creating the deployment type we can very easily identify which global contitions shold be set as requirement. But we miss a Powershell cmdlet to automize this task. Instead we rely on the application creator to remember to add these conditions.

So far I have found a PS-script that can add one of the build-in conditions, but it fails when trying to add a custom made condition.
