Switch Accounts Features?

So I have quite a few alt accounts (not for evading bans, don't worry) and have recently been using the new account switcher to get around them, which is really helpful. However, I think some more things should be added, such as...

- When you switch from account A to B, account A should not go offline and get disconnected from any voice chats.
- The ability to see the number of pings/DMs/notifications an account has from the account switcher menu.
- The option to add more than 5 accounts at a time.
