Been doing some work on our template global file lately.  And when it comes time to process a job that was drawn in the midst of these modifications, i am CERTAIN that this global does not have the changes i made to the template, but i dont dare replace it with the template version, because i have no idea what changes the draftsman who drew this job may have made.

So my idea an option to compare the current global vs the template version, so you can note any changes that will need to be remade, or perhaps something similar to when you save a subassembly where it allows you to keep or revert changes as you go.
