I have only worked on it for a couple of hours but certainly will not stop. Its fairly easy to use, even the first time, its responsive, beautiful and fast.
The only "bad" thing is the lack of themes. I searched everywhere but only found styles, which only seem to change the colours. Then there's the option of the location of the menu and also the choice of fonts.
I also saw the showcase and its like every website is the same. Can different themes be implemented and each can use the current different styles?
