Reasons why some settings should be altered:
Reset threshold, should be able to set to 100 and 200 lux. At the moment if you walk into light it takes the filter some time to go up, so 100 or 200 lux would trigger a reset faster. Also the sensor starts at 225 lux so why 400 as a minimum in the first place?
Window length, as for the above, if you walk into light a smaller window length would help put brightness up much quicker in combination with a smaller reset threshold.
If the above two settings could be added in CMParts/ODParts that be great as the filter would be much more responsive to short period light changes. For example if you go from outside to inside or visa versa.
And maybe it would even be a better idea to remove the whole custom light levels and add a linear function to it to go with the filter (configurable) and just have 254 steps (1-255) over 10-10240?
Adding 254 steps yourself is ... A PAIN ><
