We’ve been hard at work to improve the UI and get stuff into a bootstrap-based system. I think this offers a good moment to bring up the old themes and evaluate if it is time they go. Current trends in UI/UX is simplicity with a focus on the content, not the distracting colors, gradiants, etc. There are several themes I think can go:
Babyblue
Metal
Oemr
Purple
Sky Blue
Tan
Note I am working on a dark theme that would be well suited for low-light rooms and am reworking Radiant (That theme has fallen backwards a bit with all the UI changes over the last few months)
