rooms, pms, all kinds of options, modern design in a layout that worked even at 1/4 monitor screen fine.
Of course it did not work on mobile - so it didn't have to think about how that would re-arrange and look. However it is clean and intuitive for many I think.
The backend options for changing colors and making / trading entire themes was decent as well.
Can't wait to share some of the new designs with everyone!
If anyone has other suggestions or frustrations, send them to me - contacts are in my description.
