Back when Ubuntu used GTK2, the whole process of getting the entire panel to have a custom background seemed much easier with the gtkrc file. Now, with GTK3.4's new CSS files and different folder hierarchy, this seems to have been broken. Is it really that difficult for theme designers to allow a custom background for a widget, or is that the fault of the widget designers?
Moreover, I would like to be able to modify the CSS for the Gnome Panel, but I have yet to find proper documentation on the structure of the CSS files used for GTK3.4. I don't know what the files mean by "INSENSITIVE", and other terms. What I would like to know, is how to remove theming from the Gnome Panel so as to allow for semitransparent backgrounds on the panel applets. Is this possible, or will I (and plenty of other people) have to deal with this bug?
