Thanks for the feedback!
In the current 1.3 version, I've added a way to disable greying out watched thumbnails. Unfortunately for now you'll have to do it manually by opening developer console (Ctrl + Shift + K on Firefox, Ctrl + Shift + J on Chromium and derivatives), typing localStorage.setItem("dontGreyOutWatchedThumbnails", true) then pressing Enter and reloading the page. I'll make configuring this addon easier in the future.
Hope this Watched videos are now non-clickable and greyed out function have off and on to choose
