This extension desperately needs use instructions. I haven't worked out how to get it to highlight text in a webpage that matches a regular expression, which is what I want, and what I thought the description said it would do.

There's no 'use RegEx' option when I type Ctrl+F, and when I click 'Preferences' on this extension, there are no options, and nothing that says what to type to make it work. I did eventually notice the 'Regex Search' button in the toolbar, but clicking that opened a confusing dialogue box, and when I typed a very simple JavaScript-style regex, it didn't seem to find anything on the page I'm on.

Perhaps I'm missing the point of this extension, but either it doesn't do what I want, or the UI is terrible. Sorry.
