... also visible in this screenshot:
neither image nor controls are centered correctly

@kulmann As we have the toolbar on top for the pdf-viewer and text editor app, we might think about moving the preview toolbar to the top as well, easier to implement + consistency reasons

Bonus points to have them stuck to bottom on mobile screens maybe? 😉 @tbsbdr

Yes, all in for the consistency :-) I think we'll have more button-candidates for the topbar, which I would try to align to the top right, see #7160 so having the topbar as you described would be a good preparation for that as well.
