Pinning of Chats and Messages

I think it would be good to be able to Pin your Chats

i.e | you have just had an important conversation but you have a lot of other chats instead of having to find the chat all over again the next day you can just go to your pinned chats section

and Pinning of messages in your conversations

i.e | Venice just sent an important message you want to remember later so you pin it so you don’t have to scroll through your chat history later to find it
