Besides, wasn't this already addressed with steps that went faster the longer the button was held? I seem to remember that coming up, and being implemented.
All other recommendations, perfect, spot-on!
Just make the precision linked to how long the button is pressed. If you hold the up or down key for more than a few seconds, the current changes in larger steps (0.5A), then you can "click" the up/down buttons to fine tune (0.1A) the current... just like most alarm radios. There's no need to reinvent the wheel!
