Current behavior:
At the moment many components are using the connect function from redux which makes them containers.

Expected behavior:
Proper separation of pure presentational components from stateful components as explained in the container/component architecture.
It's a good idea to use styled-components for pure presentational components.

I'll be glad to work on this.
It's not completely clear how the process works to get PRs reviewed, I made a couple based on github issues last week. I'd appreciate if someone cold add me on Trello.
