// USAGE:
//   place this file somewhere in the webroot, 
//   for example in a folder named ".res" to hide it, and then
//   python3 copyparty-sfx.py -v .::A --js-browser /.res/quickmove.js
//
// DESCRIPTION:
//   the command above launches copyparty with one single volume;
//   ".::A" = current folder as webroot, and everyone has Admin
//
//   the plugin adds hotkey "W" which moves all selected files
//   into a subfolder named "foobar" inside the current folder


(function() {

    var action_to_perform = ask_for_confirmation_and_then_move;
    // this decides what the new hotkey should do;
    //  ask_for_confirmation_and_then_move  =  show a yes/no box,
    //  move_selected_files  =  just move the files immediately

    var move_destination = "foobar";
    // this is the target folder to move files to;
    // by default it is a subfolder of the current folder,
    // but it can also be an absolute path like "/foo/bar"
