If there's something I miss from Outlook its the single click to convert an email into a tasks ('Follow Up') and have it shown up in the built-in task manager. I thought this would bring it to Thunderbird, but I'm quite disappointed:
It's a great idea, but ruined by this horrible 'mails & tasks' pane that pops up and completely messes up the layout by squeezing 2 more columns where space is limited already.
I would have expected something that adds a new task into Lightnings task list and synchronizes the task status between task list and inbox somehow.
