luuuciano, thanks for the EasyTabs link, bookmarked it and I'll look into making a version with that

Seems much easier to the end user.
Might keep the old package just for users who like the jQuery UI tab control.
New idea list:
- Use EasyTabs
- Provide sample CSS file
- Allow users to add in different styles *for each theme* by putting css files in Themes/{theme}/css/tabs, html can be customised in the template files if needed
- Option to tab only selected categories
- Allow moving around of tabs
