What are the "must have" jQuery plugins? [closed]

Question

I'd like to know what are the most useful JQuery plugins. I'm particularly interested in those which are likely to be useful in general UI development, such as Tablesorter, rather than those which serve uncommon needs.

If you could provide a very brief description of the plugin's purpose, that would be really helpful.

Thanks, Don

We currently use:

Most impressive

• Layout (dock, pin, splitter) - just amazing

Jquery UI elements:

• Tabs - tabbed UI
• AutoComplete - suggestion box from web service
• DatePicker - nice calendar date picker

Useful community plugins:

• Scrollable - scrolls any div
• Scrollpane - control scrollbar appearance
• Table sorter - table sorting (client-side) for any simple table
• QuickSearch - instant searching of table content
• Validate - form validation (required / type / custom regEx)
• HotKeys - traps for key shortcuts. Captures EVERY key on the keyboard. Awesome.
• BlockUI - awesome modal dialogs
• Curvy Corners - anti-aliased by default
• Tokenised input (or Facebook autocomplete with Xs) - Facebook style tokenised autocomplete

More to come, I'll add links etc...
