If I had one wish regarding Sitely it would be a thorough tutorial video on how Layout grids can be tamed – I miss the concept in terms of responsive behaviour. The complex UI doesn’t help; I’d love to see it streamlined.
But, as said above, answering one question is of not much use, I’d love to see Duncan making a walkthrough real life video.
If I had one more it would be the same for One time animations; I find myself wasting hours without getting what I want. But hey, this one is about Layout grids – one step after the other ;-).
