for the Ui i just tryed to minimize all the pure Elements without a useage and also optimized the size mainly, since i need right klick slot for example, but i dont need my whole inv on screen.
The main thing i will do in the future is to rethink most of the parts on screen and minimize/optimize the UI spawn, aka just on screen what u realy need without any unneeded confusing information. Since i need the spell/buffnames and i dont like the transparent i choosed the best will be a viewport version.
I will try fix some Ui errors and redo some of the gfx elements, if i have time also add some special player/hotbutton/group windows for other classes (melee/pet)...
