Preset/Cue organisation with dict

Hi,

I'm trying to build an interface that organizes and edits numbered cues. As there are many cues to organize, i thought it would be great to use the hierarchical structure of dicts. After abandoning the attempt to build my own interactive dict.view in Java Script (see https://cycling74.com/forums/dict-view-with-output-jstree-attempt) i still dont really know, how to do that with the standard max objects? I've added a patch that hopefully explains what i have in mind:

I'm starting to get into Java Script for that purpose. Is there a good documentation for working with dicts in Java Script?
