Changing command prompt / Selecting current folder?

I just bought listary and I’m quite liking it so far, of course I have to get used to it to effectively use it and probably customize it some.

When I double click (or generally open the menu) in an explorer context and go to commands, I can open a command prompt in that folder. Right now it only lets me use cmd.exe, can I use a different one, like PowerShell or cmder?

Another thing I haven’t quite found out is how do I perform something on the current folder I am in, like opening the current folder in the command line for example?

Also, how can I open the “context menu” I get when double / middle mouse clicking inside an explorer context by a keyboard shortcut?
