    shell: Show annotation contents in sidebar when available
    
    Most annotations can have content associated (e.g. a comment
    on a highlighted text, the comment inside a post-it like note).
    We dislpay that content in the sidebar, as it is saves times to
    the user, and it is convenient to have there for revision.
    That is, without the user going annotation after annotation to
    review each content.
    
    Fixes #386
