Hide known character pinyin, show unknown character pinyin

I love this extension. With the updates to Anki exporting, it’s nearly perfect.

Currently we only have the option to hide pinyin, show both, and only show pinyin.
I would like it such that Pinyin is hidden on words that I have marked as known and to be displayed on unknown words.
This will improve constant recall throughout the learning experience and would be a useful feature that can likely carry on to many other languages.

Apologies if this is already in the TODO list, I searched “pinyin” on the forums and couldn’t seem to find this exact suggestion. Hope it’s novel and useful. Thanks
