I have some experience in useing ExtJS to build web-apps, so i chose that, even though it has already been use for another template.
The template will have fetures like, drag-and-drop queue, editable listviews, and i am aiming for a desktop look and feel.
The template is mainly made for personal use (and for some friends), but perhaps others are interested. ;)
I need to do some polishing and some initial testing, but i think i can post an early version next week.
I would appreciate to hear your opinions on it, good or bad

--UPDATE--
This is an early version. It has no configuration menu (It uses the config-menu from classic-template), and I am still working on the history menu.
It has been tested it in Firefox 3.6.6, Safari 5 and Internet Explorer 8 and SABnzbd version 0.5.0, 0.5.2 and 0.5.3.
The package which I've attached contains a folder named "ExtJs". It should be placed in the Interfaces folder under the SABnzbd program folder.
ExtJs.zip
Please let me know what you think

--UPDATE--
New version:
ExtJs-r070610.zip
