We have 4 columns:

* Proposed * ToDo * In Progress * Done

As a developer we mostly care about all but the first (though we drop random stuff in the first). The ToDo is always ordered with respect to priority but is generally irrelevant while one has work in-flight. That allows us to, without having to really notice, always grab the most important thing when we are free again.

As you can imagine the proposed is the ungroomed/vague/random idea list that is roughly ordered toward whatever the PO (or developers for us since we don’t have product) views as a road map - discussed every week or so.

Everything has labels and generally ties to the concept of an epic or bug.
