I am at 10.7.1 and editing is still a mess. It is a royal pain if you have ever tried to use it. I am trying to get an app up and running that allows edits of sign poles and the related signs (table in 1:n relationship class). Absolutely frustrating. From the editing widget, you can't get to the related features. If I have a pole open in the editor popup, I scroll down to the related signs and click on the link, a popup comes up that hangs and never lists the street signs:
If I start with the popup, I can click on the arrow to the right of the related signs, I can get a list of the related records that I can edit one at a time if I know which is which by default (there is a list of related records, but you can't pre-configure what that list looks like...just has 3 lines that say Street Signs.
You can change the attribute shown after the list comes up to an attribute that distinguishes it from the others, such as the UniqueID. If you click on the arrow to the right, ithe editor for that record pops up. After that, you can't get back into it unless you get out of the editor and start again with the pop-up. No moving to another related record. It is basically a hot mess. I thought the smart editor widget was going to be the ticket going forward, but nothing has changed and again, no easy way to use it for related records/Features unless you start with the pop-up, find the right related record and use the smart editor to edit that record only. Also have not found any way to relate another existing record to the feature or to add a new related record. Rinse repeat..........
