So far my only grizzle with Tuba - and it's a pretty minor inconvenience - is that composing a post requires clicking a button, which is fairly small and tucked away up in the top left corner of the app. Having a posting box as part of the main body of the interface is pretty standard for fediverse web apps, and that would be my best #HX (Human eXperience) recommendation. Failing that, make the button bigger, put a word on it (eg "Post" or "Compose"), and put it somewhere more obvious?
