Alf,
The new script is great! There are 2 items which would be nice. The first may actually be doable (I have not tried it just yet).
1. Nested tab panels - allow for multiple tabs panes with nested tab panes.
2. Cookie persistence - use the id's used to identify the tabpane and the selected tab, optionally store it in a cookie (by setting a property for the tab pane element, so it can be controlled on a one-by-one basis).
This will allow the user to go back to the tab where he was at after a page refresh/reload. Necessary in some application frameworks.
I do not know if you are familiar with the tabpane script from
http://webfx.eae.net/dhtml/tabpane/tabpane.html
but they have both features.
