The September 22 update that changed the data model to make projects optional has created a pretty big annoyance for our team. We're a single development team with a myriad of projects that we develop and maintain. Now, instead of our collection of stories being colour coded by project, we see a sea (hah) of the same colour which is entirely useless to us. The small project badge on story cards isn't a particularly useful substitute, at least not in contrast to a large band of exactly the same colour everywhere.
The colour coding of cards should ideally be selectable (team-based or project-based), or at least be allowed to be turned off entirely so we don't have to see a single colour everywhere, which entirely defeats the purpose.
This really seems like hiding proper colour coding behind a paywall, which is pretty ridiculous.
