The current time selector wastes a lot of space on the left side of the dashboard. The right side is filled with a lot of prose (30 buttons, most of them with at least 2 words). This is hardly intuitive to use. It is impossible to find the right button to press with a glimpse of the eye. You have to actually read the text. It takes a long time to find the right button to press, compared to the "1h 12h 1d 3d 1w" and the easy-to-use scrollbar of the old time selector in 3.4.
The folded menu provides just 3 buttons [<] , [zoom out] and [>]. Much better. I would suggest to add a few more icon buttons to navigate the graphs to this menu, all in one line, avoiding all the prose. This could help to avoid wasting space on the dashboard and it could improve usability.
Edit: a few keywords to make finding this easier: vertical size filter period
