The café window is limited in it's horizontal width. This is very limiting and not clearly to be followed by a user – at least as a Mac user 😉
I wanted to use tour de LC and could not see the required width due to this very limitation.
(screen shot not attached – another reauest/feedback?)
We are exploring the possibility to expand past 1024 px wide for the next revision.
Regarding Tour de LC: simply click the "Open in Browser" button and you'll be all set.
Cheers – Marc.
