Allow selecting a range of commits and see diff
Problem to solve
During reviewing, I can currently see diff of the whole MR, or of an individual commit. But sometimes commits are not so nicely made that they are individually useful, but the whole MR is still too large to check. So ideally I should be able to select a range of commits as well and see it in changes (and be able to leave comments inline there, too).
Intended users
User experience goal
The goals is for reviewer or user of web interface for MRs to have more control which diff they are looking at.
Proposal
The "Commits" tab of the MR is currently not used much. I suggest one could select a range of commits there and press button like "Show Diff" to get to the "Changes" tab but only those selected commits shown in a diff.
Currently only an individual commit is possible to be seen in the context of MR by clicking on it.
