It's quite funny that no reply was made

. I could understand that nobody's interested in it, or, it so good, that nobody can say a word ! (I know I know, I just posted it...)
Anyway, that plugin is interesting, but for my needs, I had to create a new one. In fact, my problem was that after scanning the whole mivadata directory, I had to make a fast and simple Category Tree (just like the one above), but with JSON. I don't want to load all of the data (it can be quite large) so I decided to use Ajax for every folder I open. So, in a way I open only the first level folders and that very quick.
As I said, my new jQuery Plugin is working with JSON format because I wanted to make it available for any needs (not only for directory trees but to be used for categories too). I'll publish it in a moment (it will be Creative Common Licence .. you can use it in any way as long as my copyright don't get removed :P ). I just wanted to hear some opinions on the problems (or the needs) that you might had with this kind of function.
Thanks
