Am finding the pages feature within Fences very useful - work on one desktop, gaming on another, random day-to-day junk on a third.
Just a suggestion to be able to configure different desktop backgrounds for each page - I don't know how well that suits the way people use them in general, but for me it would nicely enhance the feeling of a 'mode switch' when swiping between them.
Either way, thanks for great software overall - really helps in keeping things organised-but-not-forgotten.
