Quick suggestion: how about a click-and-hold, instead of a simple click, for buying research points (kinda like clicking and holding for spending research points)? Especially because the button for purchasing research points is located right next to the staffers' icons, it can be easy to misclick and accidentally end up buying research points (I totally didn't just do that, by the way), and once you do that, the prices are permanently increased, which can be somewhat dangerous.
