Hopefully a button can be added to memmy that quickly does this (rather than modifying my account settings). It’s nice to sometimes just hide away everything read and then bring them back quickly.
Especially because it makes it unclear whether posting is a success. I posted something and because it was deemed read, it immediately disappeared off my profile. I refreshed to no avail, so I thought it didn’t post properly and tried again. When I turned off the setting, I saw that there were two posts the whole time.
