In addition to the "Log in as ..." mode, it would be very helpful to have a "View as ..." mode available. Sometimes, I just want to make sure that e.g. a colleague acutally has the rights to view a certain contact before I share it with them. "Log in as ..." is a bit overdone for these things, especially because I do not want to do anything on their behalf and, also, I don't want to confuse them with an e-mail notification "Isa has just logged into your account". 🙂
Anyone having the same need? 😊
