I've downloaded this program and liked how it doesn't use as resources or processing time as my own program. However, I really miss the audible alert that mine gives. If you could include some sort of beep or user selectable sound, I would switch over to your app. I only wrote PowerCheck because at the time there weren't any other programs that offered this funtionality. My programming skills are limited, but you seem to have a good grasp of it. I think it'd be also helpful to release this to open source, that way it could be included in HardwareGrowl, something I already use. Thanks!
