keyboard shortcuts for zoom in does not work on german keyboard, and in general is not well usable
it would be nice if the keyboard shortcuts and buttons for touch could be rethought.
what works well: swipe through pictures what not works: zoom in on german keyboards, + is on shift-1. does nothing. 1 works though and maximizes. - i.e. zoom out works
it would be nicer if the space, arrow keys and paging could be used, and/or vi or game naviation keys. currently pg-up and left are the same, pg-dn and right, up is nothing, down is nothing, space is nothing.
