Hello,
I have some updates to circle_os next release for audio, and also think we need to make a function to disable buzzer.
I think there also are some updates for the filesystem.
Bug for LCD mirrored in primer 1.
I suggest all there has some experiences or even have made some changes for test could publish their ideas in this thread so we soon after the contest is finished can get an even better circle_OS.
I hope we can make a list here so we will not forget anything 
I will update this post and make it more readable when you start submitting changes.
Kasper
