Feature Request

What problem does it solve?

Key-value tags in a todo can be helpful to highlight. This is already done with some of the format extensions here like "pm:" and "due:" by them being stripped out of the displayed text with indicators in their place, but I'd like to see some kind of subtle generic highlighting of non-recognized key-value pairs.

How does the user interface change to accommodate this request?

A new style of some kind. It could be a new color like how projects, contexts, Podomoros, and the top 3 priorities are colored.. or it could be greyscale like due dates. Personally, I advocate for it being subtle and a greyscale style would be better. It could easily turn into too many colors and things highlighted, making it more difficult to visually distinguish important information.

Something similar to how code highlights work here would probably be best.
