Getting back to the top level menu of ALL forums is a PITA.
Simple solution, change the link on the Baloon icon to the left of the forum name to a static link pointing to the Forum top level. Save me from having to go to the drop down menu every time.
Phil,
It would be useful if we could find out why X7 does not give you thumbnails for your CPT files. I can assure you, it does work for most people.
If you can send me a direct message (click on my icon and then the big [ + Connect ] button) I'll give you a small diagnostic file that might help identify the problem.
