Clicking a new word doesn’t immediately add it to the Words tab, if the Words tab is currently open. You have to do something that forces a redisplay of the Words tab. Personally, my normal practice is to have the Words tab open and I click right in there to edit a new word that I think needs an immediate touch-up.
Then for the popover definition feature, it is very cool, but there are a few odd things:
If the sidebar is open and you have popover definitions showing, and then you close the sidebar, the popover definitions correctly reposition. But if you reopen the sidebar, the popovers do not reposition. (I don’t know what should happen if opening the sidebar causes some word to move to the next page, when its popover definition is currently showing.)
Also, the popover definitions render on top of the Edit Word dialog [and also the context list], if you open that up. It can make the dialog hard to use.
Third, an extremely minor thing, but the logic of where to display a popover relative to a multi-word phrase, which spans two lines, can result in the popover displaying in the middle of the page, near none of the words of the phrase. I don’t know if there’s an easy fix for that.
I can reproduce it on two computers. I just bring up a couple of popovers and hit “W” over and over again; the popovers will stop moving and only be right half the time.
You didn’t mention the issue of the Words tab content itself, maybe deliberately so, but fwiw that still exists. Maybe I misdescribed it, though: I think clicking a new word adds the word to the END of the list (though it will move as soon as you advance the word list page), but that’s a change in its behavior and not ideal. You’d want clicking a new word to put it at the front of the word list so you can immediately bring up the edit for that word.

This doesn’t seem to happen with deleting words from the word list, only when adding them. Navigating away from the Words tab (e.g., to Dictionary, Edit, etc.) shows the newly added word or phrase at the top of the list, as does a full page refresh.
