I would like to edit the Argos backend theme, as it again has several alignment errors I already have mentioned and corrected a long time ago, but they somehow have gotten back in the latest versions after some people changedthe admin theme core code. Anyway, I would like to correct it now, before the final 2.8.2 will be available. What is the official way to do so?
Also the default backend theme has those errors by the way.
I also wonder why the jquery tabbed backend I created (and was never adopted nor improved by the dev team) is still not implemented in this version?
