For what it's worth, Bandora appears to be a repackaged version Jammer, which I have. I watched the video, and while there have been some changes to the position of some things in the screen layout, almost everything else is the same. Jammer has exactly the same named band styles as shown in the Bandora video, the same pop-up menus, etc!
As someone previously mentioned, nothing is perfect, but I like the GUI on CbB best, and I've tried a few. I hope they never change the overall look and feel of it too much. If they want to change the technology behind it someday to make it resize more easily, that's fine. I don't think the Theme Editor is all that hard to work with, once you've spent some time with it. I'm glad we have it, I've made a custom theme for myself that I really enjoy.
