`toot tui` is a bit snappier. I think maybe they forgot the command to scroll down in a toot when it doesn't fit on the screen, as well as a command to get a pastable link to media attachments. (There's a help screen listing the key commands on "h".)
Freezes when you type "t" to look at the thread of a toot until it's loaded the statuses (several more seconds).
Seems like a promising prototype! Maybe I'll try it again in six months.
