Kind of reminds me of Alien Blue for Reddit. I hemmed and hawed about buying AB for some amount of money (I don't even remember how much it was) and now I can't live without it.
Can't say I've ever felt that way about a Mac app but I'm giving it a shot.
I've changed the price to $1.99 if you quit the App Store app and reload it, the price will be $1.99!
