Must-haves:

• Add preset times to software, e.g., 15mins, 30mins, 45mins, etc.
• Add Pause feature. As of 2017-04-06, clicking the button stops the polishing and timer doesn't remember the time elapsed to polish
• Add feature to turn on chamber light while in READY mode. Perhaps rotating counter-clockwise cycles through the different light colors. Rotating clockwise while in READY mode enables/disables the sound/beep.

Nice-to-haves:

• Have USB connector in power panel for routine software updates
• Have a "catch basin" structure in the chamber floor to collect the alcohol residue so wiping the walls and floor of the polishing chamber after each session will no longer be needed.
