Thank you for your review and remarks.
I will try to add the option to have no highlight at all in the settings (none/regular/soft glow).
Regarding your second point, unfortunately, I tested this same website, and I did not see any issue with the highlights. I would appreciate if you could, please, send a screenshot to info(at)vgreco(dot)fr
[EDIT 30/09/2024] version 1.83 can now have the highlight style set to none (go in the display options via the cogwheel) and still be able to count and select the searched words.
