I tried to add many times the Sorting of site feature on fav20, but because it is built on MooTools javascript framework, version 1.1, I couln’t do the sorting. I tried with v1.2b, sorting worked, but messed up the other code (even with compatible mode).
When mootools v1.2 will be final, I can rewrite the code to implement the sorting.
If you have any other suggestions feel free.
