I love wefwef/voyager. This might not be a normal feature people use but I love wefwef’s deep linking feature (on android). I have a push notification system for lemmy which detects incomming emails from lemmy and uses ntfy to send reddit sync like push notifications. In wefwefs case I can set ntfy to open voyagers inbox directly. Voyager is also nice since opening a unread message (or interacting with it) auto marks it as read (which I don’t believe other clients do for some reason, I could be wrong though).
