Some basic inapp commands for a controlling the app via console would be nice.
That would require the entries to have a unique id though inside the tree view.
For example:
"Push2Run.exe -list" (could list all card names with their unique ids, to be parsed by an external map to get all commands list)
"Push2Run.exe -del 2" (delete card id 2)
"Push2Run.exe -load c:\blah.p2r" (for dynamically creating cards (ex: ajax/php) and then adding the card to the app)
"Push2Run.exe -enable/disable 2" (set card 2 to active/inactive)
