One feature that would make masterplan perfect for me would be the ability to create anchor points on a board and link it to another task, like a button of some kind, maybe even a note? Then I could create indexes on the board, like I currently do with note tasks (I stack them together with indentation, rather than a full list on one note) I could click on the title I placed and be moved to that area of the board. It would make navigation easier on larger boards. Heck, even using the arrow tool to link areas together would be neat. Just some ideas on how to implement it.
Thanks for your time and such a great project!
