Thank you, it was written with SASS, but we are still working at some pieces that will let the user customize the dashboard, so we will release the SASS soon.
Have you considered playing with 4.0 alpha - hate for you to have to completley rebuild it if it is an active project in a few months when 4.0 of Bootstrap goes live.
We didn't play with 4.0 alpha yet, we wait for the official release so we will not work twice to offer support for BS4. There will be 100% a BS4 version on all our items.
