It would be useful to have customizable ticket states. I had the experience that visualizing the ticket flow as much as possible is a good idea.

My main use case is the following: If someone starts working on a ticket, it should be set to in progress. This makes it easy to see whether someone started working on something. It also helps myself to limit in-progress work and focussing on finishing stuff.

Another possible use case (but I didn’t think about it too hard): If outsiders report a bug, it should be in a state which indicates that someone from the project should triage it. For features, it should be easy to see whether something is just a proposal or it was decided to implement it at some point. Similarly, for bugs should be easy to see whether it was already confirmed or not.
