I'm sorry for my language skill, is not very fluently, as you can see

How about executing two operations by clicking one button. What I've mean is that you can put in to one button running some program and return to top-level bar. You could separate this by " ; " or another sign. (C:\Program Files\Winamp\winamp.exe; C:\Program Files\TotalComander\DEFAULT.BAR). You can even make simple menu similar to start menu, like this:
|Media|
default.bar /\ |Winamp|WMP|VPlayer| etc.
======== |...
where Winamp = C:\Program Files\Winamp\winamp.exe; C:\Program Files\TotalComander\DEFAULT.BAR
WMP = c:\Program Files\Windows Media Player\wmplayer.exe; C:\Program Files\TotalComander\DEFAULT.BAR
VPlayer = c:\Program Files\Windows Media Player\VPlayer.exe; C:\Program Files\TotalComander\DEFAULT.BAR
