Feature request: Having color as a tag

[aasiaeet]

I really enjoy the export functionality and have a suggestion to improve it:

Is it possible to have the color of annotations as tags in the exported file? For example, (Yellow), for me, means general #highlight, (Blue) is a #quote, and (Red) is a #question.

If there were an option for this conversion during the export, I'd have the above categorization automatically.

Thanks, and keep up the great work!
