maybe there is a way to mark notify threads, in the forum view with a special icon like (https://www.simplemachines.org/community/Themes/default/images/notify_icon.gif).
So the user can directly see:
for this thread I have enabled the Notify function. This could be a nice help additional to the summary in the profile screen.
I'd like to see a variety of thread markings, hope to have some time to write them as a mod once 1.0 final is released.
