I got confused with your questions, Snyder. Look again at our conversation:
Me:
On the other hand, implementing of a global copy & paste function could be something really productive while attempting to work with a couple of docs at the same time.
Snyder:
Where to would you paste it?
Me:
Example - I work with two notes: I read one note, and write second one as ad vocem to the first one. So I need to quote some text from the first note within the second one. Hence this copy (from the first note) & paste (to the second note) operation is a core activity which must be performed.
Snyder:
What do you do with the notes?
Seems to me like your questions are a kind of weird ...
