I'd like to throw a possible improvement in here for discussion: differentiation between features that you do not have and features that were not (yet) evaluated.

Currently the only way I see is checking whether you wrote something in e.g. the "Evidence" field, which can make it hard to get started again when you for some reason took a break during you assessment.

Options might be a "todo"-label (which would make the yaml searchable and could be translated into some kind of symbol on the chart - @ptechofficial was thinking about some kind of yellow exclamation mark symbol as a first idea) or simply a third state. I think the third state might make the whole thing more messy, especially because you can no longer simply check the Implementation Chart.
Additional question would be whether this label/state/whatever should then be automatically applied to all categories or if it's something the user has to add manually. In theory starting in "Todo" would actually make sense in my mind because you either want to anyways manually remove levels you do not want to assess or you can leave them in the Todo-state to signal that, while these fields are still white, it does not mean that your team/organisation is not doing this, you actually just never assessed it.

Any thoughts on this?
