Fair, though in this day and age I find being offline is quite a rare event, and when it happens (I’m driving in the middle of nowhere), I don’t need my emails.
I’ll give TB another try. Web apps always feel terrible.
It's not about being away from the internet (for me), it's about keeping my data on my own machine. I'm still trying to figure out how to delete everything from the server and still have my own copy. But that is kind of a niche requirement these days. It's better for everything to stay available on the server, usually.
