Re: [SPAM] Re: Joins on capabilities that have passed through different membranes

I'm skeptical of this UI claim. This behaviour is exactly what happens 
when people open Word attachments directly from some e-mail clients. An 
additional strip at the top says you're in read-only mode, and provides 
a button to begin editing. This pattern has clearly existed for many 
years already, and persists to this day, so it can't be so confusing as 
to be unusable.
