The former versions faked the transparency always. But since this channel is treated differently by the browsers I think it is saver to not fake it. It does not affect the security.
Regarding the missing options: only these options are displayed that are useful with the other selected options. The mentioned "ignore the most frequent colors" is only displayed in expert mode and when faking the read API.
For the default random number generator I ask you to open an issue at github. This has to be discussed in more depth. I myself are not sure what the default should be.
I tested with https://browserleaks.com/canvas and even when the "Signature" changes everytime I reload the test the "Unique Fingerprints" at "Database Summary" is always the same. Why? is this a way they can still track me??? I might improve the rate after clarifying. Thanks
Actually I'm not sure what the section "Database Summary" is all about and whte the "Unique Fingerprints" really count. Maybe they only include fingerprints in their database when they see it more than once (or the count is not live but only updated in some time periods). As the signature changes every time CanvasBlocker is working as intended. This is the tracking information CanvasBlocker protects.
Please open an issue at https://github.com/kkapsner/CanvasBlocker/issues where we can discuss the impact of that (communication is way better there).
