I'm not entirely sure how this works in the backend, but there needs to be some sort of progress bar for upgrades that are being designed.
Do upgrades reset from 0% when I assign more / less staff to it? Or does it just carry on from where the current staff got to? A progress bar would clear all that up and make it much more obvious what is going on.
It will also give you a nice visual representation of how far they've got and I think it would add quite a bit to this part of the game.
