Wow you have a good memory about the offline files...I'm impressed! Fortunately I moved away from that.
Nice to see you moved the media loading popups in bottom right corner of display when scraping to the EMM status bar!
1) The NFO data not showing up I have to blame on User error, as I got so used to having the data unhidden in my old copy that I forgot you had to unhide it.
Before I continue, all of my movies are each in their own folder.
2) Thanks for the tip about using Expert settings. After I entered the poster.jpg and fanart.jpg, click apply and OK the screen flashed like it was attempting to update but nothing happened. I had to press F5 (reload) on the movie and then poster and fanart columns were ticked for that movie and the artwork showed up. So looks like I'll have to update the entire library to get it to show up because closing and opening EMM had no effect either.
3) I've never not used AWD. It sounds like you're saying that Artwork Downloader has to be used in order for poster.jpg and fanart.jpg to be recognized by Kodi?
4) While I haven't created an NFO of each MovieSet, neither of my MovieSets poster.jpg or fanart.jpg are showing up. I have never used a common folder for any MovieSets and I'm hoping that you're not going to tell me it is mandatory in EMM, since it's not in Kodi.
5) I see that the new Edit MovieSet window has a "Search Movie" field, which was something I always missed. However, there are no movies showing up in the left pane as shown here. So no way to search for or add movies to a set. I'm using the <set></set> node in each movies nfo, and I don't use the "TMDB Collection ID".
6) If I don't enable Movies->Files and Sources->File Naming->Expert->Actor Thumbs, does that mean the .actor folder won't be created or populated?
7) Export Movies "template-moviehomepage" doesn't display any posters or fanart.
