I'm tearing my hair out on this one; I want / need / would like something akin to one of the many tree viewers out there, but where I can also edit the structure, the name and the type of nodes (the world doesn't just have folders and files, people). I've Googled myself silly over this, looked at which plugin I could modify to do my bidding (not with much luck), but surely someone, somewhere must have had the need for an editor and not just a viewer? Surely someone must have more complex needs, like me?
The best one so far seems to be the one from Bassistance, but without the good editing part (just basic stuff). Is this the one I should extend, maybe?
I'm not married to JQuery, but the rest of my application use it and it would be the simplest, but if there's a Flash or other JS thing floating around, I'm cool. Input and output should be sane, and if you got a SQL backend, that's cool, too, but JSON or XML or whatever else that makes sense, er, makes sense.
Thoughts? Clues? Suggestions?
