I don't know about you but I really work to keep things minimal on my computer, but I've always had trouble keeping things out of the menu bar. If it's not WIFI it's Time Machine or [Fantastical][fant], that's cluttering up the menu. Enter [Bartender][bar], it adds one icon and lets you bundle menu items in to it.
What I really want to talk about is the registration experience. Once you purchase it emails you the license code and shows it on the web page just like every other piece of software then it takes things one step further.
See that button, it will install your license for you. One click and it's done. Yes doing some copy and paste operations to get your license in to an app, but this little step just shows that extra care was put in.
I like to see extra thought in applications.
