Suggestion for light sensor function in v1.18: gradual adjustment

[mugamuchu]

Since v1.18 has added support for ambient light sensors to automatically adjust brightness, I consider this a milestone for the tool's convenience. Here is a humble suggestion:

Since the sensor may occasionally be blocked by objects, the immediate decrease in screen brightness can be quite annoying. Therefore, I think that when the sensor detects a drop in ambient light, the screen brightness should change gradually, with a customizable transition time in seconds. Of course, users could also set this value to 0 seconds, which would behave exactly as it does now.

Another possible approach is not to set a fixed transition time, but to limit the maximum rate at which brightness can change per second, e.g. 1%, 2%, 3% per second, or 'no limit' (user-configurable). This way, when the sensor reading fluctuates frequently, the logic is simpler and the response feels smoother, while still avoids abrupt changes. Also, compared to a fixed transition time, this approach may be easier to handle if the sensor value changes again during the adjustment process.

My reason for suggesting this is that I use my laptop’s light sensor to control an external monitor. Because they’re in different places (see figure), the sensor often inadvertently gets covered. With a gradual dimming, the user would have a few seconds to clear the blockage before the screen gets too dark, while natural-light-triggered adjustments would still work fine.
