why why why the does Thunderbird let you sort by email subject, I have never wanted to do this and I always do it if I "miss" trying to open the newest email, and when you have a 100k+ inbox this little maneuver's is gonna cost you 51 years of CPU time

@benjojo there's a plugin to prevent misclicks, makes it so that you have to ctrl+click the pane to sort

No Message Pane Sort

No Message Pane Sort prevents accidental resorting of the message pane by disabling mouse button clicks on the column headers, thus, locking the sorting order of your emails. It is still possible to sort messages by ctrl-clicking the header.

@ozone89 yooo this is useful thanks! I'll give it a go
