Yes, a live edit feature just like Espresso for Mac has would be amazing. Although to be really useful and to bring a lot of developers over to Sublime Text 2 from other programs you would need to have support for live LESS and SASS. 

I know many people are worried about slowing down the editor (Wow, it's current speed is amazing!!!), but you can remedy this by building this into a plugin, or something that you can disable to speed things up.

I know I won't be able to use this editor exclusively until it has this feature. Any thoughts fellow web devs and LESS/SASS gurus?
