File Based Watch tab in Data Viewer

Idea created by MSNThomas on Jan 27, 2017

    Make the "Watch" tab of the data viewer be file based, just like the "Current" tab. 


    If a developer adds a field to the "watch" list in the data viewer, when they switch to a different file it should just go away, and then reappear when they go back to the file, just like in the "Current" tab.  Almost anything you can "Watch" will become invalid when you go to a different file anyway, with the exception of Get functions and the like.
