When I start MultiCommander from the command line, I usually want to look at the files in the folder where I already am, however:
C:\Some\really\deep\folder\structure> multicommander
always goes to C:\ and D:\, so I have to type:
C:\Some\really\deep\folder\structure> multicommander "c:\some\really\deep\folder\structure"
which is annoying. Instead, I'd like to use . for the current directory (the way it works with DOS commands):
C:\Some\really\deep\folder\structure> multicommander .
That would open the current folder on the current drive.
Each drive has its own current folder, so from a different drive, writing c: or c:. still indicates the current folder on c:
C:\Some\really\deep\folder\structure> d:
D:\Another\deep\folder\structure> multicommander c: .
That would start left in "C:\Some\really\deep\folder\structure" and right in "D:\Another\deep\folder\structure".
