Does what it says, and well

This is a great lil app for the price. On my 15" Retina it easily allows me to switch from my usual default of the "Looks like 1920 x 1200" in the Apple Pref Pane to the Full 2880x1800 of the retina display- and the full spectrum of display options in between.

The big selling point for me was that it allows quick toggle between these "custom hires modes" that it enables and the default pref-pane based resolution. The other resoltion app, "Display Menu" gives you access to the custom hires modes but forces you back through the standard display prefpane to regain 1920x1200 hidpi mode, which is a pain after about the 4th switch.
