i dunno how feasible this is, but i'm making a request anyway
it would be really nice if we could change how our posts are arranged on our profiles; not full-on themes like tumblr, but something you could turn on or off through your settings page. multiple columns posts on profiles would be super good for artists, maybe a better way to display portfolios
infinite scrolling might increase loading times and have an addictive effect but it would be super nice if i could just scroll through my feed/profile without the pagination, specially on mobile. something we could turn on or off as well!
