Further improve discoverability of merge request suggestions
Problem to solve
Merge Request Suggestions are hard to discover in the code review workflow. The usage data also indicates adoption lower than expected, likely due to the lack discovery of discoverability.
In GitLab 12.1 we introduced a tooltip gitlab-foss#56523 (closed) to notify people once that they can make a suggestion. This increased usage from 2% to 5% of instances with usage ping turned on who use merge requests. This still seems very low for a feature that anecdotally customers find very useful.
Move the current icon button from the toolbar to next to the “Attach files” button, with both text and an icon, see design.
How will we measure success
We should aim for 25% of instances that use merge requests and have the new UI treatment to have suggested changes.
