Revert to previous pull request UI
I really don't like the new UI plus a bug in it makes it unusable (to me).
The files listed on the right-hand side (e.g. below the folder efc4c) are not in a scrollable list so I can't find comments or conflicts in the PR like before.
Please figure out how to scroll the list of files or view all the files (like before) or a way to revert the updated UI
