Application does as advertised. A great way to quickly test multiple screen sizes.

Love the fact this has live reload support now. Duo has become a super handy tool to quickly test how things will look on multiple screensizes. It has a built in inspector, like Safari’s dev tools (which are prettier than Chrome’s IMO, but not as extendable… but I love how Safari can display minified CSS as expanded).

Just a suggestion or wishlist item: I wish I could add it to my Alfred Workflow, not sure what would need to happen to add Duo to the "Open URL with” option. Maybe it is already doable and I am not accessing it correctly?
