Reviewable will now automatically group reverted and renamed files in the file matrix. This can help you quickly mark as reviewed files that you may not care about reviewing in detail.
Only files that were renamed without any other changes will be grouped this way, and if a file qualifies for both groups (as in the screenshot above) it will prioritize the reverted group. You can break up these automatic groupings with the small ungroup link to put all the files back into their original spots.
More features coming soon — watch this space!
