Not seeing indicators on the screen is not an idea; it's supposed to be a feature as the images on the Mac App Store clearly show.
Again, this is not an idea for the program. This is supposed to be a feature. Look at the pictures in the MAS; where the heck are the visible volume indicators? This is NOT what I paid for, and posting this in a useless forum that the developer is clearly not reading is also probably a waste of time. DO NOT BUY THIS!
