within my project root there is a zipfile with 10.000 java sources. I extract them to do a search in it (from outside IDEA), not wanting it as a src root.
go back to idea -> it notices the lots of new file and starts some kind of parsing. takes > 30 seconds, I wait patiently.
need to go to settings, pathes, and set the folder to excluded, do not want it to fill up my cashes etc.
need to wait again for idea to save its local history, probably pruning away the files again.
Now the dream: at the moment when I go back to IDEA and it starts "scanning" I have a possibility to press a "Stop scanning and mark the folder xyz as excluded"
... I really would appreciate such kind of improvements more than most else ;)
