On boards using complex filters, the statuses of team-managed projects are being listed in the columns settings. When you have a list of five seemingly identical "To Do's", its easy to chose the "wrong" status and have to select a whole stack of them just in case they have relevance to your filter (which in our test cases, they don't) does not seem sustainable.

Even statuses from "Private" team-managed projects are visible across Jira. It would be better to restrict the statuses of team-managed on classic complex boards
