Edit: v1.2.x is released with todo notes, which shows a badge count in the extension icon/logo for todo notes. You can use this feature to keep track of important notes.

Hi, thanks for the review. Right now, browser apis does not allow us to control notification time, and it is up to the browser/operating system to decide on how to show notifications. Acoustic/sound reminder is a good suggestion, and maybe there could be an option to configure a sound to be played when showing notification.
