Feature proposal: ability to select auto-hide timing

[giovariot]

Currently Dozer offers 2 different modes to manage the menubar: one with auto-hiding after 10s and another with a completely manual hiding mode.
I propose the addition of a dropdown menu along that option containing different values (such as 10s, 30s, 1m, 2m, 5m), as IMHO 10s is too little time while 5m would be too much, while others might think otherwise.

I'm not a developer, though, so I don't know whether it'd be possible.

Thanks in advance!
