I really like your tool. One usability issue that I found was, when highlighter is enabled and set the foreground color for a keyword to any dark color like green. Its is very hard to read the line when a particular line is clicked as background color dominates the foreground font color. I feel when user clicks on a line or selects some lines with highlighter turned on foreground color need to switched to white or any lighter color.
