I was looking for a simple, two action highlighter for reconciling two things. With this I can select text, right click, then click on PageMark, so its 3 actions - but at least it isn't 5 like some others.

I wish there's an option so the add-on doesn't change the original lay-out of webpages.

Cool work. Possible enhancement:
1. make the Tool menu available in the right-click menu of the browser button. Cause the toolbar usually hides.
2. double-click the browser button to go into view mode of the current note.
3. use page title in file name when save mark.
4. Select some text and popup a mark icon at the end of selection, click it, then mark. Like some page translate app. Right-click and select PageMark is not so handy.

nice work. If we can save the marks will be better.
