The new Software Center in 1511 should also categorize Applications using the user category even if it is not deployed to users but systems instead. It should reflect the user category no matter what.

Change default "sort by" order from "Most recent" to Alphabetic list (Application name A-Z). Or remember the setting for the client. Or allow a SysAdmin setting for site-wide default setting. It always resets back to Most recent.

After a user installs an application that was deployed as "Available", but later uninstalls the application, the user gets a balloon pop-up every time they logon saying "New software is available".

There is NO way to prevent this from happening apart from removing the user from the collection where the application was deployed, and adding them back. This has been the case since CM12 was released but this is not a desirable behavior especially when there's no "valid" way of preventing this.

Add notifications to the Action Center in Windows 10 when new Software is available

When using the client settings - computer Restart - display a dialog box the user cannot close... with a countdown interval , the dialog displayed show a hidden button that didn't work.
If people cannot hide the dialog, then why not 'hide' the hide button ? That button creates expectations that are not met, and thus frustration.

Provide a security group based method to hide software center from showing in the start menu. For example, domain users would not even see it in the start menu, but administrators would. The /ExcludeFeatures is a step in the right direction, but overkill for some customers who still want admins to have access.

Please add (display) the application revision automatically under the application that is available in software center . This makes troubleshooting for helpdesk / system admin more easy .

This will help the 1st line support to gather more client information without having to contact 2nd line specialists, and possibly solve more incidents on their own.

The Software Center, when launched, should be able to read and display client status information and connectivity with server in a simplified UI, understandable to the Service Desk employees/ 1st line support.

This can include Policy evaluation status, connectivity with management point, certificate status, app-evaluation status, etc

When choosing white colour schema you have white letters with white foreground. Would be great if we can choose the foreground colour or if the letters keep black even when you mark Items on white colour schema.

the new Software Center (v1511) should have an option to filter per category (or multiple), like you have on the app catalog website today

Users are accustomed to seeing “Last Run Time” in RAP and it was easy to sort by that column to see apps installed by date. The “Date Modified” appears to be the “last run time” in Software Center but we have to click on each app in the Installation Status tab to see the date modified info.

Software Center showing apps that failed or no longer advertised, when apps fail still show up as Available Software, could we get another category (Failed Installs) that doesn't keep popping up and reminding users. Put text field somewhere next to "Installed Software"

It would be very nice and useful for many customers to have the ability to customize the application catalog site in terms of custom backgrounds/icons or page layout.

it would be **** to have a Button in the "new" Software center to open a log-file with a Summary of the last steps that are run on a system, like for a SW installation, in a end-User readable context.
example:
SW Policy received
SW downloaded success
SW install started
SW install success (or return code 3016)
SW has a reboot pending
etc.

Administrator can define the value settings such as Business Time, automatic reboot, other.

Screen reading assistants can't parse the app catalog - it just says "Silverlight" over and over. This isn't acceptable - web pages need to be usable by the blind.
