Its not that uncommon that you have a PR where ~90 of changed files only have changes in import statements (in our case those are scala files but it applies equally well to other languages)
Its quite cumbersome to focus on the "real" important changes cos you need to find your way through all those files which have just import changes.
It would be nice to have some features which lets you filter the changed files in a PR (by some regex or so)
This way you could filter out all those files with just import changes or just whitespace changes.
Just some idea. Maybe other ppl like it as well. Should also not be too hard to implement (take the patch file, apply the regex via grep, re-apply the patch file)
