On HUM, there are secondary actions you can do to each conversation. Actions like mentioning someone at a specific point in the conversation, calling everyone in the conversation, controlling notifications, pinning and of course archiving. Most of these options have short cuts, but some we want to put in a menu to make them easily accessible.
This is taken out of context so it might be better to focus on the idea and possible execution of menu. I've currently chosen to show them in a ... and when clicked it animates into an X for close.
The animations still need some work (a bit rough and jerky). Just a proof of concept :)
