Wow, this is most definitely interesting! Is it optimized, though? Are all tabs active at once?

Also, I wonder, is this idea original or was there any attempts at making something similar to this before?

Yes, it's optimized for running multiple websites simultaneously. All tabs are visible and running, but whatever you click on becomes the "active" tab, which helps with resources. Also, non-visible tabs aren't rendered by your video card.

We didn't base this designed on any previous ideas. There have been some other attempts to solve similar problems (tile tabs, etc) but nothing that we felt quite "hit it."
