I use Bulldock Browser to create dedicated apps for the common sites I use in my browser.

This declutters my browser and give's be quick access, I 'alt-tab' to my apps.

For example I have dedicated apps for Gmail, Trello and HN (I have the HN app in compact mode, floating mode and have it auto reload 5 mins).
