Archive direct chats

I'm an early adopter and power-user of Matrix. However, I found that I am hesitant opening direct chats, and I was trying to get to the bottom of that.

One of the reasons is that I already have too many rooms, to the point that it's hard for me to find any particular room at any time. So when I am about to ask a colleague a once-off question, part of my brain goes "I won't make another room just for that".

I'm aware I can tag rooms low-prio, but that's a permanent flag.

I'd like to see a temporary flag "archived", similar to what Whatsapp does: when I am done asking my colleague, I can archive the chat, and it just disappears from my view. It still shows when I click on the colleagues profile, and should the colleague write a message, then it gets unarchived right away, but otherwise the room just isn't shown anymore.

Thanks for your consideration!
