The whiteboard view has been growing with entity trees and being able to convert notes and text blocks into entity. Its just missing something that practically every whiteboard application has: stylus input.
Example sites:
app.ziteboard.com
whiteboard.office.com
If you have a touchscreen device or a device that takes in stylus input, these websites allow you to use that like you would a mouse to draw. Feels like a straightforward request that makes sense. Hope others see this and upvote it if they have 2 in 1 or touchscreen devices that they use fibery on.
