Mark-Up Tool upgrades

Love the Idea of the Mark-up Tool but needs a few advancements.

1. Line option - make available for recipients also (put the option under the comments option.)
2. Move the Mark-up option (while in recipients hands) from the [Other Actions] button to under Add Comments icon.
3. Currently if recipient adds Mark-up to document, next signer cannot visually see what was covered. Within the document, wherever there was a Mark-up added:
   1.  add an Icon to the left of that Mark-up and add a feature where the next signer can click on that icon and the mark-up will briefly disappear. This will allow all parties to view the original language.
   2. While other parties can edit other people’s mark-ups, you can delete all, change and revise, however, you can only change or revise within the size of the original mark-up’s box size. Allow this to be resized. 
   3. Require all signers to initial mark-up. Any Changes to mark-up, needs to be rerouted to all who have not seen. (similar to the collaborative option of text fields)
   4. Allow any user to reject just the Mark-up...or allow it to be deleted from another signer
4. Allow SENDER to change mark-up formatting if they want, particularly Font Color.
