you can kinda use the levels system to do this. have level 0 have no censoring, and when it detects body parts you configure it levels up to a censoring level. and once you stop the level will decay back down to no censorship
In the case of this option, the program continues to weigh down the computer unnecessarily, as it is constantly analyzing your screen and using a portion of the hardware, and may cause incorrect readings on unnecessary pages.
My initial idea is that you can leave it open in the background without affecting the use of your computer, so you can play a game or work with "100%" of the computer free, and when you open a certain page, it is activated by the extension that is in the browser itself.
This creates a false idea that you don't have control over the censorship, because you don't need to keep opening the program to activate the censorship and then have to close it to use the computer normally.
