Since the sensor is a hardware trait, I can’t change it in firmware. The most I can do is change the thermal regulation algorithm…

… which is very tricky to do well.

It was recently rewritten, again, with the help of pakutrai (08-15 User). The test results are posted here. It’s still not perfect, but hopefully over time it can keep improving.

In any case, the thermal code isn’t really part of the UI, so it’ll likely be unaffected by the UI changes.

Given that the D4 can start fires in like 3 seconds, this is a question of full power or safety. On some lights, it can’t really be both at the same time. However, on other lights like the LT1, full power is pretty safe. So it has different settings on different lights. When it can be safe at full power, it allows full power by default in the simple UI… but when full power is definitely not going to be safe, it doesn’t.
