@mglukhikh: Just got to test the platform type inspection.
First of all, it's working nicely.
One minor inconvenience I noticed is

Also, I noticed when the inspection is invoked on multiple files, you can select all occurences and apply

, but nothing will happen because it requires interaction. Can this be fixed on the inspection level or is this an IDEA thing?
