By default, the Workspace Palette is a waste of screen real estate and valuable palette dock real estate. It's rarely used in day to day work here. While it's functionality could be argued, I do not think it is necessary to give it such a prominent default position. Sure it's easy to turn off, but if everyone is doing that, maybe it shouldn't be there to begin with?
Personally, I would just eliminate the Workspace palette all together and use the Workspace menu at the top to access those. Or even just have it turned off by default?
Furthermore, I think it would be great to have an option with all of the workspaces combined into one Ultimate, power user workspace. Most of us using FormZ for a long time do not need to hide functions, and the side toolbar has plenty of height available for more default tools to be shown (on a 1920x1200 screen). This side toolbar could just be better divided to show which tools applied to their 'workspace', Drafting, Animation, etc. Because right now their is other dead space below the sidebar that is difficult to make use of.
Overall, there is a lot of wasted space in this UI design that should be easily fixed.
