These would be really powerful in providing more information while keeping the board clean.
Background: I've been using MindManager extensively for over 20 years and the branch notes (along with the ability to link directly to local files) are one of the features for me that make me prefer a MindManager map to a Miro board for certain use cases (e.g. developing concepts or personal knowledge management).
PS: It's not about comments, these are a different use case. It's more like the description field on cards.
