TL;DR
Please make research window not popup if I currently work with blueprint.What ?
Please make research window not popup if I currently have blueprint GUI opened (like I'm making new blueprint - setting icons, naming it, etc...), instead open it when I save blueprint (Check icon), or cancel it (Q) (= when I won't lose my work). Maybe even also postpone this window while I'm dragging blueprint rectangle on map.Or, if you prefer, make blueprint GUI stay opened behind research window, so when I select next research and close it's window I can finish my blueprint.
