I think it would be useful to borrow the Lock Workspace feature from Photoshop for After Effects, esp with the wide use of so many scripts and CEP panels in many workflows. I accidentally pull off tabs or slide them around in my day-to-day use of AE, esp since I’m using a Wacom pen most of the time.
I’m sure there’s some wrinkles to consider, esp when switching Workspaces while locked - do you prompt with a pop-up or automatically switch it?

I would go even further on this idea, Ryan. Not only being able to lock the workspace but for example a preferences option, limiting the number of maximum comp-tabs you can have opened in the timeline panel. Nuke has this feature to avoid a crazy amount of uncessary node panels confusing the user while working. This in AE would prevent an user needing to scroll to X amount of open comps in the timeline, looking for the correct one, and having only a chosen max, of the recent ones.

You can set your own workspaces and rename them. If you mess things up, you can quickly reset the workspace to the last saved state by double click on the title tap. Hope this helps a bit?
