It is a lot better than the old default template... it does lack a bit in the styling department, you could do a lot more with just JS/CSS/HTML. Its even possible to do fancy gradients with css that will work in all modern browsers. But I suppose it is still quite functional. I would offer my help with the template styling, I just need some more motivation, working on profitable websites at the moment so open source stuff takes a back seat. I am trying to organise myself so I can get back on here though.
I like the use of selection on the table rows, its almost exactly how I was going to implement the selectable archive download on our templates. I may just copy it from this haha.
Also I don't know how long hot linking the jquery api will last... would it not be better to use sections for the javascript, like you do the stylesheet. I know it'll mean the template is big and ugly but you could just place the sections under the core of the template so the user doesn't see it initially. My main worry is, we accidentally left a hotlink to a jquery plugin and the bastards modified the code to 'Rick Roll' everyone doing it. So all the sites running on our work system were being Rick Roll'd. That was not Google, I doubt they would do that but just a warning for the dangers of hotlinking lol.
