After writing down a paragraph in a specific color (lets say black), I would like the ability to select a tool (maybe one that looks like a lens) and would allow me to go back over the words I have already written and change their color to something else (such as blue or red). That way, I would no longer have to erase something and rewrite it in a new color. It is different from the highlight tool because I am not suggesting adding an additional color, rather I am suggesting the ability to change the color of these pen strokes.

Therefore if I had a full paragraph written in black but I wanted to outline a few key words, I can use my lens tool to drag it over certain vocabulary words and it would change the color to blue.

Would be extremely helpful when taking notes in class and you dont have the time to switch between colors while a professor is talking. Would allow for edits and quick corrections after the fact.
