I’ve added mockups demonstrating the appearance of the presentation when an embedded one is maximized. Since it is pure HTML, it is not going to be opened in a different window unlike a Flash video, it is rather going to overlay all the page.
todosOverlay, the overlay plugin used on the intro page of ToDoSo, is now an independant project since it tends to become a full featured overlay plugin. It is now possible to use the keyboard for navigation and I got rid of some graphical glitches. I’m quite proud of its look & feel. The idea of using buttons looking like keys is likely to be used again in ToDoSo since it seems like a great way to make keyboard shortcuts discoverable.
