I've had my "thread saving" setting on "forever" since the assistant first started saving threads. As you can imagine, my list of threads is now very very long. Now I want to change to using the "24 hour" setting instead and use the neat "preserve" button if I want to keep the thread. But this only applies to new threads.
So now I have 100's of threads that I would like to delete. As you can probably imagine, going through each of them individually would be unbearable...
I would appreciate an option to be able to delete all threads in one swoop!
This option should only remove non-preserved threads. If I have some threads now set to "preserve", those shouldn't be removed.
