I would like to see everything becoming a bit more KISS. It seems (or at least I feel like it) like were drowning in tools and relying on them too much. I mean more in the sense of Grunt/Gulp with PostCSS and thousands more of dependencies and plugins.
I think there's more people wanting to go vanilla more and more and by that I don't mean just JS, but CSS too.
I'm hoping that the forest of frameworks will shrink a bit, so that choosing one will be easier. It still feels like there are frameworks coming out each and every day though.
