Proposal Shaping and Notes/Mind Maps/Categorization-- Better Ways to Write it All Down & Visualize

As we shape our proposal together, does anyone have a more creative and efficient method for visualizing all the dimensions we’re discussing? This would be for a virtual environment. I’m finding it challenging to use the Zoom Whiteboard for moving text around, recategorizing, and creating an organic image that reflects how the group shares dimensions. Any suggestions?
