There should be option to hide OSD when mouse is moved/clicked/over osd.

Big, long visible OSD is great when I'm away from keyboard and control foobar with remote. But when I'm working + listening to music OSD is sometimes annoying and obstructing view.
Making OSD mouse-phobic would be easy solution for this.

good idea. But i would like to emphaze that this really should be an option, since the fact that you can curretly still access apps which are "under" the OSD can sometimes be a great "feature" - especially if you have the opacity of the OSD set to a low value.

true. window transparency (for clicks too) works great. but you cant make osd text transparent

May be I understand something wrong, but you can make OSD text transparent.

You could make it transparent.
Goto the OSD-Preferences and tick the check 'window' and move the slider to left of the check.
Press 'Test' and be happy

yes, technically you can. but i ment that transparent text is unreadable.
