[Seaside] Ajax-y JS components?

[Boris Popov]

I was googling around last night and lets just say that I expected to 
find more interactive components readily available on the web by now. 
Scriptaculous is a step in the right direction, but things like in-line 
calendars and tables with column resizing and reordering seem be 
something that everybody grows in-house. We recently installed FogBugz 
issue tracking system and I find their tables particularly well-done, so 
if you know any place I could go to download (heck, even buy) some, 
please share, pointers will be greatly appreciated.

Thanks!
