I'm not sure if it's something that I'm doing wrong on my end, but I've already twice tried changing the alert sound from the default 'ding' (ding.mp3) to my own alert sound (alert.mp3) using the method described in the settings page, and both times Chrome kept automatically disabling the extension after a few minutes have passed, saying that it might be corrupted, and forcing me to 'repair' it (which seemed to be pretty similar to a full reinstall to me, since it got rid of all my history/data :( and reset the options to default values). So yeah, I've given up on changing the DING for now xD
