I personally think this would make this timer indispensable as it is something that I cannot do with a normal kitchen timer and it would mean that I'm less likely to inadvertently perform an inversion at the wrong time.

Can you confirm that the end of process sound is different to the 30 second beep?

Currently the device beeps twice on the minute, once on the half minute. Variable beeps I'm afraid are not really practical - there is a time display so you can keep track of the minutes, or if you're tray developing in total darkness with the display covered you could use the cricket umpire method of transferring marbles from one pocket to another in order to keep track of the minutes . The end of step beep is longer than the agitation prompts, and is preceded by a ten second countdown.
