With Signal, there is no way to see who has received or read messages, which is especially annoying considering that they have a "mark as read" button on the notification (at least on Android). This is terrible for group chats, because you can never tell where people are in the conversation. Allo, Hangouts, FBM, and WhatsApp have this feature, why not Signal? Well, the developers say it would lead to reduced overall privacy. But that's only if you make it apply to every chat by default, when they could fairly easily just make it so the user can specify if they want "read" status sent per chat. This is restricting Signal from being used at least by my group of friends, when we are all very privacy minded. We want to use Signal, but features that are just lacking like the inability to have "read" status in groups is holding it back.
