I'd like to launch geany in a specific directory from the command line, and then use a keyboard interface to open files from that folder - I've done something similar with Atom & VS Code using the Ctrl-P popup. Launching it from a specific directory does seem to work - the tree browser plugin shows that directory.

It seems like the commander plugin is what I want: I can assign a keybinding for 'show command panel (files only)'. But this doesn't seem to expose any of the files from the working directory, only menu entries related to the word 'file'.
