Taking Ajax higher with next Rails release.
Thomas Fuchs has been doing awesome work building on top of Prototype (the Javascript engine driving Ajax in Rails) to bring us script.aculo.us: Better effects and dragndrop capabilities. Together with the upload progress enhancements
from Sean Treadway, were going to have a big upgrade to the Ajax
capabilities of Rails in the next, forthcoming release (0.13).
If you want to see whats in store for you, checkout the addition of dragndrop to Backpack. Shows off very nicely just how cool dragndrop can be in a Web 2.0 application.
Theres more chatter about this on Loud Thinking, Signal vs Noise, and mir.aculo.us. [Riding Rails]
