You should add some screenshots so people can at least see what you're trying to sell. That's one of the first things I look for with anything like this so I can get a feel for what's being offered.
Otherwise maybe it's prematurely on HN if you wanted to get best value for hitting the front page?
Definitely needs screenshots. It's nice to say that you can "manage your pages clearly in tree structure" but I'd like to see what it looks like without trying.
Also, it definitely needs an "About" page. Who are you people?
