Reviewer should be able to give positive feedback on code sections
### Problem to solve
I as a reviewer would like to give positive feedback on good code.
This would increase motivation in the team and would also make clear that i appreciate some nice refactoring (or maybe the use of the boy scout rule)
For now I "only" can start a conversation which normally means there is a problem (otherwise the resolve feature don't make much sense).
I'm currently using the conversation function as a workaround to give positive feedback.
But it feels wrong, i always have to resolve it myself and then it's not longer visible in the MR overview.
### Intended users
The feature should be used by all reviewers. And the MR Authors would of course see the outcome of it.
### Proposal
The simplest solution could be a thumbsup button which could be placed on a line of code. (maybe with a count in case of multiple reviewers)
It could also be a textfield which is shown in green in the overview.
I think it should not be a discussion and there is no need to make it "answerable".
### Permissions and Security
Every Reviewer who has the permission to start a discussion should be allowed to give positive feedback.
