The big problem I experienced with every plugin I tried either using Prototype/Scriptaculous or jQuery is the customization. They say you can do whatever you want simply but that's not fully true. The default CSS works fine, but most of time it's a mix between required elements and optional. That mean you have to be very careful when editing it.
The other problem is the animation. That's the worst point. I never found one plugin allowing to redefine easily the animations.
I tried to solve these problems with my plugin. I documented everything possible. The default CSS contains only optional rules. Without it, the plugin will works perfectly —but will also looks very sad. Regarding the animations, you can simply redefine them from A to Z. Thanks to the useful jQuery function like animate, fadeTo or the future enchant, it's pretty simple.
Moreover, I added the ability to define many callbacks at different time in the process to allow you to edit the settings, the data or do whatever you need.
