Suggestion: When highlighting text, you want to use "multiply" blend mode (a.k.a. subtractive color mixing) instead of opacity. Opacity makes black text lighter/greyish, which is not how physical text markers work, or colored sheets of transparent plastic.

Thanks for the suggestion. I plan on having user selectable blend modes. Currently, it's using the "difference" blend mode. This mode makes it easy to spot shifted images.

I've just implemented user selectable blend modes. I've included the multiply mode as well. Thanks for your feedback.
