I'm not sure whether the other commentors (especially the ones with low rating) had the right expectation.
For me it's an online IDE. There's no support for "I don't know CSS, help me to style the button". That's not what the product is intended for.

It's like Visual Basic oder Dreamweaver in the cloud with hosting included.
I did some projects with it and I even used the hosting, which is fast and reliable.

It's an awesome tool.
I'd personally wish there would be more options to rearrange, reorganize files (multiselect and so on)... But if you know what you're doing and are dev-oriented it really works great.

It does what it says it does and that for a very nice price.
Grab it while you can!
