Everytime I want to open a FXB or FXP file, I have to browse through directories. Renoise should be able to remember what directory you last used for opening a FXB or FXP file for EACH of your VST’s. Shouldnt be too difficult to implement, but would make my day! 
very good suggestion. right now I made a “banks” dir on c:\ with all banks in it, but its still alot of clicking around.
