## Proposal
Across repository and code review pages, the menu options vary. We should audit and simplify/unify the options.
For example how we call the action to edit a single file
| Edit in Rapid Diffs (not in prod, gdk only) | Edit on Blob/Repo |
| ------ | ------ |
| {width=596 height=306} | {width=561 height=600} |
