Hi,

many skins (like text2skin, enigmang, soppalusikka, ... ) support displaying a graphical progressbar when a text like "[||| ]" appears in a menu item. Since runtime patching a font is not possible anymore I was wondering if also the skins classic and st:tng could support this. Here's a small patch (based on the sources of enigmang), that adds this functionality. Would be nice to have this in VDR core ;)


Regards,

Christian
