Hints for fields I’m creating. I do a lot of work for clients and I can inline instructions for them, but once they get used to it, those instructions are just in the way.
So if beside, say a field for adding a date, there could be a little circle with a ? they can hover over / click on and it pops up a little bubble that reads “Enter the date for the start of the event”, or whatever the message would be.
So, these would be configurable in the Custom Fields editor, and viewable / hoverable in the actual Post, Page, etc. editors.
