Example 1 To ignore a thread:
In Agent Press 'I'
In Pan it's Ctrl-Shift-I
Why so much more complicated for a common event? When Pan does ignore a thread, it stays in the count, so you don't see from the summary that there is in fact nothing to see. It will also chunter away for a few seconds with the screen flashing while it actually marks them ignored.
In Agent, it just ignores them.
Agent will also delete, or mark as read the line, and any other parts of the thread that is collapsed. In Pan, you have to delete the first, then go back and delete the rest.
And don't even get me started on email readers....
