Looks very nice!

Maybe small adjustment so it's not vertically jumping between view and edit mode when the toolbar pops in:
In view-mode, in the space where the toolbar is, it could show the document name (in bold, left-aligned). Is that possible @juliushaertl?

Not a blocker though.

Yes, though I'd file as a follow up to get this in rather quickly

[jancborchardt]

In that case all good design-wise. :)
