This the Core addon for BobUI you can download the full suite here
BobUI is a Default UI replacement addon written and intended to be as light as possible on memory while still retaining the functionalities of a fully usable UI. If you break it down it's pretty much the default UI skinned by !Beautycase and has a few added bells and whistles.
Known Issues: Nameplate castbars look like crap Aurora Skin is not complete (I'm still working on it, it may take some time)
Upcoming Features: Expanding skin support for other addons Diminishing Returns (there is beta code on BobUI\modules\diminishing.lua)
Please post all bugs/issues/qq/death threats in the comments.
