Ableton Live uses 3 file browsers and i think it,s a good idea to make filebrowsing to different locations a bit faster. we just have to look and see what is the best way to do it. If we implement multiple filebrowsers (there do not have to be actually 3 filebrowsers implemented we just need to remember the location of the 3 browsers) or we implement some way to do favorites ... hmm
it,s on our todo list ;-D
