Your placement of various "nyms"

It might be good to collapse by default only where they exceed a certain size. If we are collapsing a small handful of words that don't take much space, then it is counterproductive to make the user perform an extra click/tap to reveal them. But if it's a big paragraph, it can be helpful to hide them by default.

A bit of CSS could be added so that the height never exceeds one line. The expand button could then change this so that it slows everything. However, if there are some people who'd rather not see the nyms at all by default, that could be made into a preference.

Yeah. The CSS idea isn't bad. Preferences are nice for regular users but they don't really solve UI problems because some users won't find them, some won't want to create an account, and some use a ton of different devices and can't conveniently be logged in all the time.
