I love this extension, it's one that I've been using for a long time and it's perfect for me. However, I wish there was a toggle to turn off highlighting images or youtube frames or maybe a whitelist/blacklist option? so that this extension would only work on certain websites of my choosing. that would be helpful. Another feature I wish to see is the ability to edit the colors. I wish I could maybe change the font color or the opacity, this would be helpful because sometimes highlighted text doesn't show up properly. Other than that, I have zero complaints. It really is a nice, feature rich extension with an intuitive interface.
