At the moment, revisions seem to be for just the main Hudu data.
It would be great if there was a separate history or revision on a card (or integrated to the main asset) so that any/all data is logged upon any sort of change.
I'm also thinking it would be great if this was configurable per field (or some way to mark a field as minor) as with Office 365, I want to see all contact info/license changes, but, I really don't care too much about 0.1% of mailbox usage change...
Even better though, it would be good if it did log everything, as long as there was an easier way to compare revisions as it would be a nightmare to go through hundreds of changes when looking for something specific (e.g. a slider or archive.org style - click on a field and see all points in time).
