Sorting by recently modified should mix files and folders

[jancborchardt]

Currently when sorting by recently modified first shows folders and then files. Rather we should mix them, whichever item was modified most recently. This is the same we do in the web interface.

Because right now the sorting is very strange for folders with a lot of items and folders – you need to scroll down a lot to get to the relevant items.

But this is the way other file browser do this, oder?
(I can only verify this for dolphin [KDE file browser])

Desktop file managers might do that, but on mobile it’s impractical. :)

Ok.
Then we do it 👍
