anyone knows how does this perform compared to http://ace.ajax.org ?

this uses codeMirror as a core editing component ace is faster and more code friendly than codeMirror. (multiSelect, indentGuides, folding) but codemirror is smaller and supports variable width and bidirectional fonts

currently there is no comparable desktop project using ace but maybe there will be something soon http://www.indiegogo.com/happyedit
