I should be able to add multiple unconfirmed (white) mental notes to the same space.

I should be able to add unconfirmed (white) mental notes to the same space as a confirmed (green) mental note.

I should also be able to place the note on the list of features in the top-right corner of the on the board, not just on the movement spaces. For example, I should be able to place a note with "1-7x" on the "Subversion Bookstore" area in the top-right corner of the board to indicate the recruiter didn't visit any books during the first 7 turns.

Actually it's not enough, that's precisely why! Just for context, the reason I wanted multiple notes is because I got an early miss for some feature, so I added a note like "1-7x" in a space. Then later I wondered if it was move 8, so I wanted to note something like "8?". Then later I used the Verizon lady's can-you-hear-me-now ability and got a miss for the recruiter currently being present in that same space, so I wanted to note something like "9v". (I still hadn't found the recruiter's starting path, so the "1-7x" and "8?" were still relevant). Basically I couldn't fit it all into 6 characters so I need to be able to have multiple notes, or longer notes, and/or ability to note "1-7x" on the feature in the corner of the board (instead of having "1-7x" on each space with that feature).
