@jasperblues About the code review process. Need a refresh of my memory. Did we decide on to always mark issues ready-for-review before closing it, then someone else in the team review/close it?

[jasperblues]

@eriksundin yes we decided to do that. . . This is a really simple one, but I guess we could stick to it out of consistency.

@eriksundin

So just for clarification, the process is.

• Finish a feature. And push to main branch. Mark it 'ready for review'
• Whoever is around can review. Reviewer can either close it (simple case) or b) raise for discussion. in the latter case we'll try to gain consensus before closing.

This process helped a lot with eg #138

Great @jasperblues, thanks for the clarification. Yeah, figured this particular issue be somewhere in the grey zone. I think its good to stick to it if it's at least a change of some extent and it's not a question of a github issue-less refactoring or change.

Yup we may as we'll just follow it for all tickets great and small. Even if the implementation approach is simple/low-risk it'll keep each other informed.
