Sometimes when I fit my ship, I purposely fit modules that I want to take with me (for possible use on the way) even though it’s going to give me the ‘Information’ popup that I need to click away. I could place those in the cargo hold, but then I’d need to dock to refit when I do actually need it (but then Murphy’s law regularly acts up, so there isn’t always a station in the system 
). So I just fit it, and when I need it, I take some other module(s) offline and put the one I need online.
EDIT: Hence I was thinking, would it be possible to skip the popup message when fitting modules by holding down Control (or Alt or Shift) as I drag to fit it ?
The more important checks, like whether you can fit the module at all on your ship, would still prevent you from fitting it ofcourse.
Also, there’s still the check when you undock, to see if you’r not overfitting your ship, in which case you can’t even undock. These checks will prevent any abuse of this feature ( I hope), so there wouldn’t be any problems I guess.
Thanks.
