Apps Question about a dev tool (HTML5/jQuery users)

[SweetLavender]

I recently came across a dev tool called "DaVinci Studio"...it is something like Sencha but based on HTML5 and has a jQuery framework. There seems to be a lot of features that sencha does not have, but I haven't been able to try it out since the Mac version hasn't been released yet.
Has anyone tried it or have any opinions on it?​
