Asking for freehand drawing annotations markups using layers on existing diagrams or new diagrams maybe even convert freehand text and shapes from a known template once ideas are somewhat finalized. Seen this feature for an ipad/ios14 on latest WWDC demo english and chinese text and shape conversion. Collaborate using layers pinned to the participating collaborators - fork decide which layers to keep/review. One of many possible uses cases "What about that idea we had a couple weeks ago can we pull up that drawing or layer (freehand drawing or annotated drawing)?"
During covid19 WFH policies and working in a global environment any news/updates on this feature from your Product Team?
Would be cool and extremely practical.
