Nice product, waiting for V2
Useful, simple to use, efficient and surely much more.
On the nice to have side, I would ask for the colour.
One of your features is to annotate a document. Having the colour, one could much more easily highlight the annotations in a document, presentation, plans ...
Concerning the Marker, except the better feeling when handling the "black" one, I'm still wondering what is the real difference.
Very good and efficient concept, I've already saved a couple of trees.
Thank you
