> the lack of syntax highlighting on merge reviews is a killer feature
Creating an issue for this and scheduling it. I agree we need this for diffs => issue here: https://gitlab.com/gitlab-org/gitlab-ce/issues/3292
> Also multiple assignees on MRs
We solved this with the 'approvers' feature. We still want to only have a single assignee, as only a single person can click 'merge'.
> Ability for anyone to add labels to an MR, not just the assignee
This should be anyone with editing rights to the MR, such as masters. We're improving the UX to make this easier in GitLab 8.2 or 8.3 (also creating labels on the fly and quickly adding more).
> On the index page listing MR's I've often felt like a solid improvement would be to show both author and assignee. I think Gitlab has alternated between one or the other a few times on this page but both seem to me to be pertinent information.
Currently both are shown: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests
One is inline, the other as icon. Let me know how you think we can further improve this.
