I use Freeform for a vision board. I also have board for a bunch of different tattoo designs I’ve found online that I like and am using for ideas of my own design.
What may be more unique is I’ve started a board (WIP) for our home landscaping. What makes Freeform ideal is you can zoom out to see the all of the landscape and then zoom in on a specific area to get the details on individual plants. I will have notes on each plant. I’ve already found it helpful when I’m out in the yard and can’t remember some detail about a plant I pull out my phone and drill in to find it.
