Hey,

We'll have to have a look at this, because we kept the settings pane simple in implementation it might be more difficult to do this.
We could rewrite it into a simple React app which would make this way easier.

However, we also need to translate menu items and the like if we go this route so requires some thinking.

T.b.h, doesn't have the most prio for me personally, sorry.
