NicePanel provides an administrator the ability to create as many top and/or bottom sliding panel tabs as (s)he wishes. Here are the features:

-Separate top/bottom panel configurations
-Automatic tabs - based on the module title
Preserves Javascript events (unlike some other panels)
-Independent left/right tab alignment
Independent tab styles
-Tab content honors Joomla ACL

Here's how it works -

First, take the modules that you wish to be presented as tab panels, and assign them to a new module position (you can just type it into the module configuration). For simplicity, I'm going to call the new positions "nicepaneltop" and "nicepanelbottom" - but in reality, you can name them anything you want. The module order will be the tab order (if using right tab alignment, the tab order is reversed)

Then, in NicePanel configuration, set the module position to be presented in the top and bottom panel positions. Save it.

You're done. Panels with no pain.

I've added the ability for an administrator to use the CSS textarea applied by the plugin, or to turn off the styling portion so the panels can be styled using the template stylesheet. NicePanel is light - no additional JS frameworks required - NicePanel is pure MooTools.

Version 1.13 - Joomla 3.0 compatibility update
Version 1.14 - hides the panel when the site is offline unless a user is logged in
Version 1.15 adds options to hide the panel on chosen templates, and for mobile devices (phone, tablet or phone & tablet)
