Quote Emails In Reply
Since we receive emails where people respond to quoted parts of our emails, we’d like to be able to reply to them the same way without copy and pasting because, after doing this, it messes up the formatting and looks too jumbled. And, if you overhighlight and hit the delete key, it archives the message (on the MacOS App).

Gmail allows you to star one of the many messages in a conversation. Starring the whole conversation is less useful to me as I want to single out and highlight one specific part of the communication.

Would be nice to be able to have Google Calendar as part of Missive so that I do not have to keep a separate window opened to view my calendar.
