I'd love to see a built-in step to add information to the SMSTS.log. Basically just a single-line text field that would parse TSVariables just like any other step that has text fields.

This would allow:
1. Easy way to dump a specific TS variable value at a specific point in time to the log for troubleshooting.
2. A potentially easier way to search the SMSTS.log file for a specific point in the task sequence. While you can search for task name, there are many entries that contain the task name - you could make the content of the step unique enough to find.
