Update: To be fair, it's not exactly a 'theme'
Works well for mass converting sections & it's definitely a breath of fresh air that's got me back into using OneNote after staying away from the bright terror for a while.

Suddenly colored text has a lot more meaning.
I tweaked the macro settings to use my preferred colors. I'm wondering if there's a good way to include URL re-color?

Thanks for the effort on this!

This is a great theme but it would be great if it "stayed" applied. It works for existing text, but it has to be re-run to apply to new text.
