When presenting or screen sharing a Miro board, there isn’t a great “pointer tool” besides the mouse cursor to facilitate what is being presented.
The idea here would be to have a temporary/auto-fading highlighter/pen tool so that it can be used as a pointer tool by actually drawing on the Miro board.
The temporary nature of the highlighter/pen is that it would auto-fade away after a period of time (something reasonable like 30s or maybe even configurable).
This would allow for a worry-free drawing/highlighting mode, without affecting existing board or having to erase afterwards, that greatly aides in visually effect by indicating/drawing directly on the board.
