Hi! I'm exploring going back to using a standalone email client rather than a web based client, and have always had a soft spot for Thunderbird. I view my email on a portrait oriented monitor, so horizontal real estate can be a real asset - My folder pane on the left side only takes up about 25-33% of the vertical space, and the remaining space would be ideal for me to pop my events/calendar panel into, and then have the rest of the screen for the actual email list and content of emails. Is it somehow possible to move these panels? Most other applications would let me drag and drop things like that, but I can't seem to do it with Thunderbird. Not "complaining" - just noting. Thanks for your kind thoughts.
