git-future-blame see inline blame view for open merged requests that change this line of code
Release notes
Problem to solve
When I'm using git blame in the UI I'm often trying to find the right people to contact about understanding the code and recent changes. It would be even more useful and serendipitous to find there is another developer currently working on exactly that line of code. This may save me time as they are the best person to ask a question or I may learn from an open MR that they are trying to fix the same problem I'm looking at. At present there isn't really an easy way for me to see who is editing a file or line of code right now.
Proposal
In the git blame view in GitLab we could have a way to show that there is also an open MR for that line of code and link to the MR.
