A somewhat common workflow for me:
- I get an email about a new bug (A)
- I click through and while reading the description in Maniphest, I realize it's the same as an existing bug (B). B probably has a lot more context / discussion alread, so I want to keep B, not A.
At this point, what I want to do is, search for the existing bug and mark the current task as a dupe of the existing bug - while on A's page, search for B and close A as a dupe of B.
But the currently supported workflow is:
- open a new tab
- find B via some search
- from B's page, go to merge duplicates. Probably switch tabs to find out what A's task number was, and switch back, find it via search and then merge the dupes.
