Mac OS X and the applications running on it are known for being sometimes unusual in the look and feel. For some reason developer on Mac OS X seems to be more creative than on other platforms. For an application developer which deals with user input it is important to make any user interaction as useful as possible and present this information in a way which is on the one side as much less annoying as possible but also attractive and informative on the other side. Lastly I was thinking about how to show the users they are using a beta version, which should remind them that this is not production ready software, but on the same time make it easy to respond to bugs they find in this pre-release. The solution, I came up with, was a badge in the toolbar which shows this is a release which is definitely in a testing phase, but also allows the user to double-click to give a respond to this particular version. In the following post I will show how to do this.
