As an agile team member I need to be able to see all swimlanes on a board even if they're empty.

We use the swimlanes to reflect the branches we're working on issues. This works really great but has the disadvantage, that the swimlanes aren't shown, if they are empty. As we don't want to use numbered branches, it would be really cool, to have the possibility to show all swimlanes even if they are empty, if I want.
