In My Opinion, I believe the User Workspaces could be reworked. With the current system, there are some missing options, such as custom resized windows, and multiple Workspaces. I understand you can add separate workspaces on all your monitors, but it would be nice to have more workspaces available than what displays are connected.
It would also be nice to create screen layouts, so you can tell the software which screens have what layouts. Think of it almost like MA or Chamsys
