No gonna lie @904331 that my post had some pun intended to be provocative in it’s style, to force an answer 
I really do hope, you will find yourself limiting to add new functions just “as of yet”, to at least allow (stable or beta) release of 3.3 or 4.0, so we can start working on something, especially 3.2.10 is unusable for now due to mentioned bugs. Adding features later on can always happen.
For the screen and requests provided:
I can’t see sector indicator in Controllers lists.
Will windows be part of API (so we will be able to create own ones?)
I know that icons are bitmap hardcoded, but are windows colors will be changeable? I know system used in HUN are green, but in many places - don’t And this color itself is little distracting for some people. If this was changeable, especially with advanced colourings (like in symbology), this would decrease amount of required “raw Windows API” drawings made by plugins.
