I think there’s 2 good types of UI:
1) one that is so simple that it works for everyone without thinking, on-off is one of those glorious UI’s, but ramp up-ramp down is another one. There’s no objection against safety measures going on in the background, like reverse polarity protection, LVP and thermal management.
2) a UI that can be configured to anyone’s preferred simple or difficult UI, so also the ones in 1) , but any variation should be possible. Key is that once it is configured, you just notice your simple UI and no surprises happen like unintended strobes or blasts in your face. I was very charmed by led4power’s LD3 user interface, although it is a clicky UI.
(If the BLF-A6 driver was available in just ramp up/ramp down with background safety stuff, I would swap all my drivers.)
