Logically agree, it’s a good contra, but not very good, because:
- Most of all I like style v4 - when message controls appears at the right of the post, so vertically they can be placed “as lower as possible - at message end and screen bottom”. Controls panel can even dynamically vertically fly at each message vertical place most close to current mouse position!
So this is not a problem. - Most users who write and read big posts - for answers use the exact text quotes, or always can answer to topic itself - thus “Answer” button is not very necessary.
- As I say previously about “for mobile” - because of absent of right side free space and touchscreens - main controls buttons still must be displayed always and at standard places - seems it’s the best design for a vertically narrow mobile screens.
- You always can prefer v3 where main message controls stay at bottom or something similar.
So if you prefer to keep message controls at the bottom - it’s OK, but I still ask to help to minimize all free vertical space above&under them and display controls (except Likes/Edit) only on mouse rollover (for desktops).
