Better build-in caching engine

Yes yes, i know that TyZ created great engine, but it only caching .swf files not xml, or html when SEO is "true"
Of course there's a few tricks to avoid this, but it would be very helpful when something would be build in Gaia core

And more...loading selected files in background would be another great feature

Check out the greensock loading classes.. you can use that to really help loading assets "in the background' if you so choose to do so.... its what i do ... and seems to work ok for me Not too sure about the caching issues.... not a issue for me, never really looked into it.

cheers.
