## Problem
Bot comments can be very noisy and take up a lot of visual space on MRs, making it harder to go through human-created review comments or other status updates on an MR.
**Example**
<img src="/uploads/cb21c0f5fdc43ffedd6991d2559d29f1/Screenshot_2023-08-03_at_12.18.28_PM.png" alt-text="example bot comment" height="400px"/>
## Proposal
Allow bot comments to be resolved/collapsed, at least by an MR author, if not by everyone with developer role.
