Add hyperlinks not as comments and bring the watermarks feature from the web standalone version

it would be useful to add hyperlinks without having to add it inside a comment bubble that is visually too powerful, (light blue and it scales up whe you zoom out). or change being able to change the color and apperance of the comment buble (a point, a transparent rectangle etc.) Another thing is to have a watermark on the page itself like in the web stand alone to add logos or instructions.
