Hi, Thx! Yeah we are working for spartan support. I hope we'll support it in few weeks. Can you please send us a more feedback? We need all opinions to make Last.Backend better and better.
the biggest problem while using Project spartan is that the left side bar menu is not working properly, you can open them and then you can only see is the "Add new image" button, which doesn't work in project spartan either, but otherwise it seems everything else seem to work like it does in Developer edition firefox
