Those screenshots are in reverse order I guess.

Mobile interaction is that the first menu is just completely replaced by the second menu. Ideally there would probably be some kind of fancy animation or something, but I think the behavior is relatively reasonable overall.

What do you think of just accordian-ing down the list instead of a new popup?

Basically just revive D8685?

Which do you prefer, I assume this?

I'm fine trying either.

Let me try that again, I don't love this particularly.
