Drag attachments from Missive into another program
Most email apps I've used me to drag and drop files from the app straight into another app or website. So I'd expect a file can be pulled from Missive, for example, and dropped straight into an upload prompt on Dropbox or WordPress website. In the current version, however, drag and drop only works from Missive to Finder. Drag it anywhere else and the other app doesn't recognize that I'm trying to drop a file on it. So I have to drag from Missive to Finder, then grab and drag from Finder to the app I need the file in, then go back and delete the app out of Finder because I didn't really need it there in the first place. Would love to eliminate all of those extra steps :D
Automatic follow up if no reply
This could be a killer feature for Missive: https://www.ifnoreply.com/ :)
Chat read receipts
As a team communication tool, it'd be helpful to see when my teammate has read my chat message. Not sure how this scales to many teammates, maybe similar to a group Messenger conversation? (showing people's faces at the last message they've read)
Search within selected conversation
Please allow to search within specific conversation window. Right now, we can only search emails but what if we want to search within specific conversation window (created using the two comments icon on top left corner - left to pencil icon).
Highlight terms in search results
The search function returns a list of conversations and emails containing the query but it doesn't highlight them inside the conversation. Conversations can be very long may not even load the portion containing the search terms.
I'd like to run rules on emails that already exist. Not just on new ones. That way I can lable all old emails that meet a certain criteria.
One click unsubscribe
Would love to see a one click unsubscribe feature that can be seen in polymail, etc.
