I just hat to switch from Altap Salamander to Directory Opus and what am realy missing (besides other) is the fast drive change with Shift + Drive Letter (e.g. Shift-C > Drive C, Shift-H -> Drive H, ...) - is this possible with DO9?

P.S. Nevertheless DO9 is nice compared with Salamander, but what's missing (for me) is internal ISO, 7z support and proxy support with FTP
