This was reported in an earlier variant (couldn't find the post) but the mission editor isn't resizable laterally or there is a limit that needs to be greater. To replicate, mouse over the left or right side of the mission editor window, notice you get the windows resize mouse-over symbol. Now try and click and drag to resize. You'll notice it doesn't.
This is important with units with long names as you're usually looking to know the host unit at the unit. In this case, I've got a bunch of cap missions and I want to pick the closer host base. The unassigned unit list has a slider but every time you move it down you also have to slide it over which leads to 2x clicks. If you have a lot of units and unavailables it's pretty cumbersome.
If you could make the mission editor window growable horizontally or laterally that would be great. If you can't but can allow the Unassigned Units list to be vertically scrolled without having to scroll laterally each time that could a solution too.
