We’d find it useful for one user to be able to edit a pinned note created by another user to append information to the note, or to allow multiple activities to be pinned at the same time.

Hi there,
it would be quite useful for us too to have an option to pin multiple aktivities, like an e-mail protocol and a note at the same time.
I know we may use comments under the mail, but in our pinned notes are much more information about a company and the information in the comment section is more attached to the mail directly.
So pls make it happen 
BR Dimitri
I hope it some day will be possible
