Merge #gmail and #googleplus!
At this moment I have 'messages' (=emails) in GMail and 'messages' in G+. And G+ sends me a 'message' to GMail that I have 'message' in G+!
Next step is messages in G+ that I have new email in GMail? ;)
I can 'tag' (=group together) messages in GMail and in G+ I can group messages in 'circles'. "Те же яйца, но в профиль" :) Make circles hierarchical (for advanced users), call them ... 'tarcles' and viola.
I can attach pictures to emails and put video links, and for receiver GMail shows pictures and expand video links inside the message. And difference from 'sharing' in G+?
Yes, I can attach any kind of files (documents) to emails, but I can't do this in G+. But wait, may be I can? I'm on iPad now, I can't check.
+GMail and +Google+ are just two different looks/views of the same information. Merge them.
