Notes Pop Up & Checklist on Mind Maps & Flow Charts for Project Management

I’m a recent Whimsical subscriber and love the speed & ease at which one can create a flow chart or mind map.

IMO there is a huge opportunity for users to utilise Mind Maps for project management. I myself have have created a few - BUT I would love the following added features:

Ability to have a large pop up notes screen on a mind map branch or flow chart box. Purpose of this would be to add more depth, URL links, checklists to the mind map branch title.

Planning and organising projects in this manner visually has many advantages, esp. for teams and collaboration.

Please let me know your feedback on this idea.
