Adding whitelist addresses to Deadalus

Wouldn,t it be great to be able to add your personal whitelist of addresses to your Deadalus Wallet. Your friends, family, and exchanges you use. It will bring extra security, and protect you from making costly “errors”. If sending to an addres outside the whitelist requires an extra step ( like F2A) then it gets harder foor malware to rob us of our ADA. Would unybody else support this idea?
