This is a minor issue and there are surely more important questions to be answered.
But I am using the Nerdery CP theme and noticed an issue with the UI of the Grid fieldtype.
When I try to reorder Grid rows (in EE 2.7.3 and 2.8.1), I cannot drag rows between other rows, they just jump to the bottom or top of the set. I made a quick video to demonstrate: http://youtu.be/p8-5OjqnDd0)
If I turn off the Nerdery CP theme, then the reordering seems to work fine (but that's a drag -- so to speak -- because Nerdery looks so much cleaner and less pink).
Alas, the Nerdery devot-ee forum is archived only, so I was wondering if anyone has noticed this issue and possibly resolved it in the override CSS?
