For some weird reason I can't see your comments on the GitHub page,
maybe because the commented line was removed ?

Jan-Christoph might be right about needing to have rows with bigger
height for external storage admin as well. But that's for another PR, as
the external storage config itself has many other UX issues that need to
be addressed.
If we agree to make the row height bigger, we'll remove the small
spinner as well.

On the other hand I don't think that configuring external storage on
tablets is as big/frequent a use case as the files list.
