It would be nice to have a little button next to a research to spend all my KP directly. Without opening the Research and then clicking the button. Would save one click. ^^
I mean I normally spend all my KP directly on one research. Does someone just spend one or two and not the rest?
Implemented: you can now invest as many KPs as you have, or however many are needed to complete the research - whichever is the lower amount - with one button.
