Weird header bar on empty state

[bertob]

On the empty state the headerbar contains a number of inactive controls, which looks weird and is a bit confusing, especially since the text on the green button is illegible.

The right side of the headerbar should just be emtpy when nothing is selected, like e.g. in Fractal.

This looks much better, is that what you meant?

Also, button fixed

The headerbar needs a divider between the two sides, but looks much better otherwise!

Funny enough there is a divider there, but for some weird reason it was brighter than other dividers. It's fixed now.
