Javascript to write for views 2

Here is a list of javascript widgets that need to be written for views 2:

1. A checkbox associated with some set of other form items. These form items are either disabled or invisible when the checkbox is not checked.
2. A select box associated with some other set of form items. These form items are either disabled or invisible unless some set of items are chosen in the select box.
3. Both of the above are done
4. Tabs are being worked on. There are two phases, first being finding the right one to start with, second being adapting it.
5. Modal dialog, with ajax forms. We can require the jquery_forms.module and other plugins in a similar manner. The modal part is done. A dialog can load from AJAX. Now I need to get the jQuery forms working with it
6. ajax list management: Note I have code for this that's quite generic and we can probably re-use. I've seen it and it looks complex. I'll investigate a little more but wouldn't mind writing my own
