Combined external and internal editor

[RasmusLindroth]

Allow for editing inside of tut and with an external editor

Speaking about editor....
Unlikely for external, but couldn't the internal editor not verify user accounts and properly link them? Certainly it cannot pull all the usernames, but perhaps at least the followers and people following. But I am not sure if that data can be API-pulled.
Then the internal editor could behave on something lets say I type: "This message was written with @tut"
Then I will get a drop down if there's no direct hit with all my interacting users that match and contain the phrase 'tut'

Just thinking out loud here.... ;)
