URLs (Am I the only one who likes to know where I'm going when I click a link?)
@handwaving Microsoft introducing "safelink"s in Outlook that were impossible to scan as a user was one of the most frustrating changes they made to email.

@runewake2 @handwaving arguably even less safe for attentive users.

And unusable with plaintext mails, I hate it.

@climbertobby @runewake2 Yeah I can imagine this is super annoying. The unfortunate result is that it would teach me to just click on the link to my the "safelink" go away (which is not great!).
