As per Mike's reply to a thread I opened, I think that I great idea for an addon is a wider support for "Watched things" over xenforo.
I can see a tool like @Xon stuff, called "Watched Essentials" that could:
- Apply specific forum nodes auto-watch for specific groups
- A way to manage the watched things from specific groups and members.
I might help funding a bit or at lest buying a premium resource like this.
