The main problem is that vertical sliders and horizontal time investment bar show both the same info but with different values. Could be more usable when all this is shortened to horizontal bar with controls and divided to 10% blocks scale above it (like ruler). Top section can be used for stuff combinig and some statistics maybe (features reqs, stuff output, etc.).
List of my stuff at the development stages should show when someone is on a vacation. Makes it easier to switch since the office is overlayed at this time.
Place “Menu”, “Settings” and “Help” buttons somewhere for dummies. And maybe some more controls always visible with notifications for publish/contracts. Sure, I know that dropdown menu is a feature, but it could be shortened to personal menu for every single worker. Unlinked actions should be visible, I think.
It’s a bug but goes in bulk: I need “windowed mode” setting saved between game sessions, please!
Training courses are repeatable and static. As I want to see it - many different courses but once for a worker. Can’t remember me being trained the same course/learning the same book even twice. Reference myself to it - yes, but not fully repeating it. G3 training should not be affected, though, it’s fine as it is.
Adjusting development screen size to fit into minimal game window size is not enough - can’t see left part of stuff list and right part of features list. And the minimum window size to fit it into edges is too big for my video player for Star Trek: TOS, it’s overlayed by the game. =(
Many other good suggestions were made before me so I won’t bother to repeat it.
