Echo JS 0.11.0

A quick note to people having problems (osx) with earlier versions; It's much more stable / usable now. Many thanks to developers behind it.

Slow and buggy, for me at least. I will continue to use Sublime Text 3.

That was true for me when Atom was around version 0.6x through somewhere in 0.8x. Now Atom is very fast, and not that buggy.  
  
In some areas it is better than Sublime Text, and other areas it is worse. I do expect it to leapfrog over Sublime Text pretty soon though, Atom has the advantage of momentum on its side.

Sure if it can get to the same performance i think it will be a winner.

Somebody that used it can say about it in comparison to Sublime Text and Brackets ?

It's extremely similar to Sublime Text, ST is clearly the model Github is basing it off of.  
  
It excels over ST in package management and discovery (built right into the app with a very nice UI), much better project wide search, and I find it is easier to hack on.  
  
Sublime Text so far is better at multiple cursors (although Atom is fast catching up), is a bit faster over all, and its fuzzy file search is better. But, I don't think it will be too long before Atom addresses all of those and more. I have no doubt Atom will ultimately make Sublime Text irrelevant.

Oh golly just what web-development needed another notepad with colored text.
