Apologies if it’s in the wrong place, but there wasn’t a more specific category.
I usually down hosts for maintenance when no-one is around, rather than on a schedule.
It would be nice to have a figure somewhere for total users currently logged in so I can see at a glance how many are going to be affected.
So for example. A host with 10 instances, 10 total users each, with 27 currently logged in would show Users: 27/100 or similar.
(That, or a detailed list-view of instances showing ports/users/RAM/CPU, etc rather than cards like currently 
)
