I would like to further customize the Toolbars.
I run a machine shop. I only use Model, CAM, and rarely Patch. When I am moving between Workspaces, it's not a quick movement, as I've got to click on the icon and then scroll down to the appropriate tab and then click again.
I would like the opportunity to do one of the following: 1) Let us "turn off" those icons for Render, Animation and Simulation. 2) If that does not appeal to the developers, let us assign a hotkey, such as Alt+Tab, or Shift+1, Shift+2 etc to instantly select the workspace needed. 3) Let us arrange the order in which they show up, so it's a shorter mouse trip.
Also, there are icons that take up real estate that many simply will not use. For myself in particular, I'm looking at the whole "Make" button, which has the 3D Print, Proto-Labs etc. Not needed, not wanted, let me remove it (but!, give me the option of putting it back at some point in 4 years when I get a 3D printer)
