Really like it so far, I prefer it to Waffle which we been using. Only problem is I can't figure out how to edit the content of an issue once I opened the card? Edit: Also trying to figure out how the Review state work compared to Waffle.
I'm not sure what you mean by your second question. On Zube, the In Review doesn't have a concrete meaning, that is, it doesn't affect the card's state beyond who the issue is assigned to. At Zube, we use the Review column for cards that we have completed but still need to test, have code reviewed or just want to keep an eye for unknown bugs.
