Using the groups tool (actually only looking into it. I commonly have a browser tab with faithlife.com open instead of this - I feel that's better use of screen real estate) I've come accross some quirks:
Community Notes View
Group Tool's Community Notes view - in both By Recent and By Books view - gives a much different look & feel as the CN tool:
- it uses a different font (looks like Times New Roman) versus the CN tool (looks like Arial or such), even in the blue action links which usually are button-like fields in other Logos UIs
- bug: the CN titles are missing completely
Community Notes view By Book
- first doesn't show a button to collapse the notes per book (which will work by clicking on the title)

- then shows two different buttons to expand:

and it constantly turns a green "loading" circle - even in collapsed view - why? (btw, my log believes the application to be idle, and my cef.log recorded the last activity hours ago)
that's how it looks on the website (the green circle only displaying very shortly):
News View
Not a bug: The News view does show the group's News, but it seems it were showing the CNs, since creation of a new CN now creates a News item, too - don't know when that started but it's probably a nuisance for group members who get their Faithlife news feed flooded. I first thought it to be a bug but found the website works the same way.
Documents View

Description issue: I think this is most probably not a bug, but works as designed, but it confused me.
- When the Groups Tool's Document view says there are no documents, this is inconsistent with the group's Documents tab.
- Dragging a document (such as a PDF) from Windows explorer into the area which claims we could do so to share it with the group won't work
- What I think is going on here is that the Groups Tool says "documents" when it actually means "Logos documents" (as the purple box in the screenshot from the website clearly says). This would be perfectly okay in L6 if not for the fact that Faithlife groups do have a Documents tab which allows sharing non-Logos documents. This needs to be renamed to "Logos documents" in at least the two lower marked red boxes.
Logs attached, in case it helps finding out more about the quirks: 2134.cef&logos.log.zip
Edit: no change in 6.5 Beta 2 (not expected or announced, just for completeness sake)
