I understand that Listary6 is still beta now. Since there’s no update details between beta versions (I’m using beta, and get updated as soon as there’s a newer version), So I hope you don’t mind me asking, is there any news on this topic?
As for how to open command line in certain folder, currently I use Cmder which has an option to open in the current folder. See here on how to set up Cmder to start at a certain directory. After setting it up, you can search a folder in Listary, then use Ctrl + O to bring up the contextual menu to open start a command line in the folder selected (see image below).
