Yes, there's no direct messages!
1. "Private Mentions" is......is just a simply fucking posts, but limited to only specific users to view!
2. Have you been a Twitter user/Pleroma+Soapbox FE user/Friendica user?
2.1. Those are social media that gives the DMs the best look.
3. No, Matrix (why on the Earth do people keep suggesting it with its broken somewhat "E2EE", when you can't restore your DMs, if you unable to?????), even Matrix doesn't gives the look I would like to have. Come on man, just check out Twitter's way on designing DMs. Alex Gleason (founder of Soapbox FE) took it and now Pleroma instances that are using stable last versions of it, are having DMs to look like....I have no idea to say it in other ways, but......just like chats!
Long story short: DMs in #Mastodon should look like DMs in Twitter!
(And yes, I still call it #Twitter , not #X !)
Friendica and Pleroma (stable versions + installed Soapbox FE) are only those #Fediverse social media that did DMs to look more like DMs from Twitter.

P.S. Please remove your CW when you'll reply to me - for some reason Mastodon copy-pastes automatically the same text from previous CW. Thank you!
