Is your feature request related to a problem? Please describe.

Element currently has a labs feature which allows you to pin important messages in a room, and then view them in their own menu in the top right (similar to how it is in Discord).

Describe the solution you'd like

Something along the lines of a button in the top right of a channel (next to People and Options) to view pinned messages, and a button to pin a message if you have the right permissions.

Additional context

This is done using the m.room.pinned_events state event.
