I am suggesting an app that allows editors on the move to have a way to handle URs and PURs while away from the computer more effectively. This could also allow PLs to be opened and segment(s) involved to be edited easier from the mobile device.

URs could have notifications and work like a chat room that other editors can join.

PURs could have notifications with the ability to approve if info can be confirmed while mobile.

PLs could open with options to change the lock level and see segment info upon scrolling down.
