Save function is sporadic (particularly for checkmarking items).
It doesn't seem to be able to highlight abbreviations like U.S.
Adding words is confusing.. just add a word after a space and then bump it to the next line with enter.
I'm afraid that I will have to keep looking.

It does what it says. Doesn't seem to be the best looking, and some of the instructions for things like the actions are not as understandable for someone who only knows the basics of browsing the web. I installed this to see if there was a specific feature, but sadly there is not and will be removing it. It seems like it has been a while since there was any updates, but if you are still supporting this, it could be a useful feature to add an "Action" to show a specific note that you have typed up when you click on the highlighted text. With that feature alone, I know there are 30+ of us that would install this immediately. Again, it does what you have intended it to do, and might be exactly what others need, just not me.

Works great!

Great add-on.
But I think URL blacklist is not working globally (blacklist per list is working)

avatar Carlos Le-Fort

Excellent application. Exactly what I was looking for.
