It appears the configuration settings reset after each quit. Not sure if this is on the _to-do_ list but it's somewhat of a pain to set them each time (let alone remember to). Also, the recording frame is not remembering placement either.
I'm on an older mac btw – Late 2011, Yosemite 10.10.3
Hey @tdreitz, #75 should fix this (not in master yet), however, we're trying to decide if the window position & size should reset on Quit. For now, we've decided on _yes_, but could revisit. I will take a look a persisting these:

The configuration settings could be remembered (aspect ratio, size, etc.) while the actual position of the selection area should reset on every quit. Thoughts @tdreitz, @stursby?
@skllcrn that's exactly what I was thinking... working on a new branch now 💪
Fixed on v1.0.0 😄
