Add Editing Tool to Digisign

I agree with a previous agent.  It would be VERY helpful to be aple to "Mark-up" and edit a document.  Example:  I would like to cross out a line with a color OTHER THAN black and then write words near that in a color OTHER THAN BLACK.  

Currently doing that using the "Writable" option in Digisign and only being able to use black makes it difficult for others (agents/clients) to see when making multiple changes to a document.  Having different color availability would be helpful.

Also, having some basic clip-art shapes like an arrow would be nice as well and a highlighting tool.

Thank you for your time!
