How about the first checkmark indicates delivery and the second "read". do you guys care about the "it left the phone" state?

Personally "It left the phone" state is very important to me, esp., when I am travelling and network connectivity is intermittent.

Also "Message Read" is a very ambiguous state according to me - If the content of a message is read from the notification drop down, but user never opened whatsapp to read it - is it read, or not ?

Definitely. You want confirmation it got to someplace same until delivered to the recipient. 1 check for got to server, 1 check for delivered to recipient device, and then "Read" underneath the furthest part of the conversation that has been read. Or I'm just crazy and niche.

I'd say: clock symbol till it left the phone, one checkmark for delivered, another one for read.

Perfect!
