[MlMt] opening messages?

[Sparky Doosan]

New user here, this looks like good software. I'm confused though, 
double-clicking a message seems to want to find related messages, right?

Why does opening a message seem like a thing most people don't want to 
do? I'd expect to double-click to open the message and view it... the 
preview pane is good but not how I normally view my emails.

Am I missing something? Probably a ton of things, ha. Thanks!
