Hi. I wonder if you have checked out WikiWand, which does something very similar to Winter. It could be interesting to see what features they've implemented and how relevant they could be to Winter.
What's interesting is that the website claims to increase Wikipedia load speed by 3 times, which is astonishingly fast. I wonder if the Winter team could look into what makes Wikiwand faster, and maybe implement something along similar lines to increase speed as well.
Yup, WikiWand is well known (well-sold? :p ) and all possible questions have been probably answered. Imho the greatest difference between WikiWand and Winter is its target: Winter team works for contributors and readers when WikiWand team seems to underestimate "Edit" button (are they aware of the existence of our community?). This fact excludes WikiWand from further discussion. Moreover, projects that aim to modernise MediaWiki interface are numerous (I think there was an analysis of them!). WikiWand wants to be known as the most 'trendy', 'cool' etc. WMF staff was improving MediaWiki design before it was cool :p
