I have been trying to get a unity like interface with Gnome, but the Unite extension doesn't seem to work with some applications. Most notable are firefox and libreoffice. The close, min, and max buttons should be on the top bar but are still on the window for some reason. I see that Unite requires some xorg or x11 dependencies on the gnome extensions website. Would downloading those fix the issue and what would that package be named in the solus repos if needed?
