I’ve checked several in-app user feedback frameworks, but found Tyler Hall’s OpenFeedback most usable - the code is very readable and consistent and it’s visually appealing as well. However I’ve been missing crash reporting option, so I’ve decided to roll my own.

Recently I’ve come across Justin Williams and Martin Pilkingtons posts describing their solutions about working with Core Data in single-window multiple-view applications.

In a project I work on a need arose to have iPhone like on/off switch including the animation. Since I already use Core Animation for other purposes, a custom layer was immediate choice. I was bit surprised by not being able to find an example on internet, so I rolled out my own. In this post I’ll demonstrate the implementation I chose.

Most modern Mac applications are designed around single window / multiple views architecture. Examples are iPhoto, iMovie etc. Although this results in more streamlined user experience, it brings some issues for the developers.
