Just posted to IdeaScale, upvote if you like the idea:
If the Montage/MODX could output complete XML descriptions of a Performance to a flash drive, that would enable comparing two similar Performances (using a diff utility) to see the details of where the settings were different. There is currently no easy way to do this.
Allowing input of XML from a flash drive could enable some interesting possibilities as well.
Another possibility would be input/output of XML via the Montage/MODX Connect utility.
(I also proposed this idea to John Melas for inclusion in his Total Librarian and Performance Editor.)
