It would be helpful if the visual colour schemes (aka Themes) could be project specific. That way if I'm running more than one related project (as suggested in advanced tactics workshops) it's really clear which project I'm hopping into. One would be sorbet themed, the other forest themed (or whatever the user chooses). The theme stays and is maintained with the project, with a default theme for any new projects, of course. I've already had a few times where I have revised boxes in the wrong project accidentally.
