Shapes and Sticky notes should be able to have links associated with them. I understand that you can embed pages, tasks, docs, etc. It doesn't have the same utility though.
When creating a flowchart or a concept map, you should be able to click the item to open a task, document or external link. If this can't be done, the next best thing would be the ability to change the size, shape and color of a bookmark and clickup task within the whiteboard.
If I could mind map and expand each card to view details, that would make this so powerful. I'm not really experienced with whiteboards but this translates to a multi-dimensional mind mapping ability in my head. Maybe this is already a common thing with other products for all I know They could even link to other whiteboards. I have a complex business and automation strategy I'm working on and this would change the game for me.
