Walk through the MR discussions related to your user
### Description
When working on the release post, it's always a mess to find where discussions that still require your attention are located. That's mainly because of two factors:
1. discussions can be expanded or collapsed
1. jumping between unresolved discussions is not optimal if there are a lot of discussions still running
### Proposal
Do something similar to **Jump to the next unresolved discussion** that brings you only to _your_ discussions. Definition of _your_ could be discussions that you started, discussions that mention you, discussions that you already commented, or any combination of the above.
~~A more extreme approach could be having tabs for "your unresolved discussions" that just shows them. Or even, "show only unresolved discussions".~~
I hope the need is clear, solution is still to be defined.
