The video is really nice but the site is really hard to navigate. The scrolling on the front page is really wonky (I use a regular mouse on PC and I have to scroll the wheel about a dozen times before the page goes down), browser back navigation is totally broken when you have the menu open, the menu is really hidden it almost feels like you're not supposed to use it. I was trying to find the list of features and it took me a while to even see the menu with the features page. Maybe add a "see more features" on the front page where you list the most important ones to take you to the more detailed view.

The app itself is very nice.
