The changes to the hints so it shows up on the right side of the page were, at first, very annoying because when I clicked Yes, I then seemed to have to work within that very small area to make my changes, additions, etc.
After a few frustrating hours, I simply clicked on the document link at the top of the hint 'screen' and was immediately taken to the more familiar 'screen' to add the information, pretty much as usual. I'm sure others have discovered this 'workaround', but just wanted to leave this here in case others haven't.
Cheers all, from a very frosty, locked down, Toronto!
