I like #Matrix and #Signal both for group communications, but there are still many things that #email does much better. For example, I often want to quickly preview a message to see if I want to deal with it now. If not, then I leave it marked unread. Not possible all the messenger apps I've tried. That leads to slower response times because I won't open messages until I'm fully ready to deal with something more complicated. Maybe #DeltaChat is the best direction for the long term.
@eighthave Curious, how would you suppose Delta Chat could implement "mark-unread" in its UIs? Some of us recognize the use case underlying mark-unread (and use it on regular MUAs) but for a messenger-UX it's not easy to implement "mark-unread" -- maybe there is something better like marking a message with "todo" and having such marked messages appear in a special "todo" chat, and clicking them transfers you back to the chat-context of the message?
@eighthave @delta as much as I dislike Slack, they do this. Alt-click on web, long-press on mobile, then "Mark unread". It moves the "unread" line to just above the selected message in the chat/thread
