Depending on scale and other factors, the link arrows can be obtrusive while editing. It would be ideal to have the option to turn them off or on as needed in this mode.
Thank you for your request.
I filed a request in our internal tracker to provide this option.
As may know we are a small team and there are currently a lot topics that we want and need to address so it might take a while until we get to this.
I agree. This would be a great help. Just adding the ability to toggle the display of these arrows would make it so much easier when designing mockups. In particular, when adding a link to an icon, the arrow currently completely obscures any small icon.
