A couple of functions I would find useful for a project I am working on.
1. Being able to set your preferences in settings so that the markup styles stayed as you set them for each sheet you move to to markup.
2. Setting up a drop down menu where you can select which type of review you are doing and the markup palletes changes to those pre-defined settings. For example, we have set a review process with certain colours/highlighs/lineweights etc a drop down menu that would show checker/back-checker/originator automated tool palettes would save a lot of time when reviewing a lot of sheets.
3. Being able to set the markups to published instead of always reverting to private, a lot of users forget to change this simple step and the markups end up not being visable.
