What I mean by this, is there a way to add something to differentiate two or more different projects that are currently open?
Right now, all projects (and folders and timelines) all use the same overall interface color. It would be nice to make a second project use a lighter interface color, or to have those elements have a thin color border or text color on the tabs be bright blue or green or whatever. I already did the thing that lets you specify the highlight colors, so I figure there might be a way to independently set appearance colors per project.
