When I want to perform a directory diff I must (AFAIK) first start eskil and then click
Tools - Directory Diff
in the menu, which leaves me with the first eskil window empty and unused (since I'm only interested in the directory diff window). So it would be nice if I could start eskil with an argument saying that "I only want to open the directory diff utility", for example like this:

eskil -d

It would also be nice is there was a help text when trying to send arguments to eskil. When I try
"eskil --help" or "eskil /?"
I get no output at all. Perhaps eskil doesn't accept any arguments in current version, but even if so, this would be nice to know at the prompt. For example like this:

eskil --help
Eskil Version 2.6.2 2012-06-18
Command arguments are not supported.
