        Certainly that would be much richer graphically :-)

        Sounds great to me.

        IIRC this may be an artifact of the UNO interfaces involved - it was
prolly easier to code this way. Also - if you have multiple
presentations loaded concurrently, there might be some fun ergonomic
issues :-)

        It's a great idea; I'd love to see that. Prolly it intersects nicely
with Artur's work around protocol expansion - I imagine we'd want to
have new methods to query the open presentations, get notified when new
ones are opened, and render the first slide of each (?).

        I guess we would want to either have a special-case method to get all
previews of open slide-decks (and notification of when that changes).
Adding a new integer index (eg.) of "which presentation" to all 'get
preview' methods is likely to cause grief around re-numbering them /
sticking with the same presentation when others are loaded in the
background I imagine (?).

        Anyhow - nice work with the iOS remote ! :-)

        ATB,

                Michael.
