Pinned messages in chats

[cammellos]

As a user
I want to be able to pin messages
So I can welcome new joiners with important information
So I can keep important messages visible

Description

We want to allow users in a group chat to pin messages.
This should work for private group chats, one-to-ones and community chats.
Public chats are excluded.

The way it works is that pinned messages will be ordered just like normal messages, but will have a different visual
indicator (i.e color and a label) https://www.figma.com/file/aS1ct66VQ6V0cio7vSqS8UoG/Chat?node-id=18553%3A60460

For each chat type, there will be an entry point to see the pinned messages:

For one to ones, is under the profile of a user (NOTE: profile always shows the pinned message between you and the other user in a one to one chat, regardless of where you access the profile from)

For private group chats is under group info: https://www.figma.com/file/aS1ct66VQ6V0cio7vSqS8UoG/Chat?node-id=6942%3A35457

For communities chat is under the chat details screen (not existing at the moment): https://www.figma.com/file/aS1ct66VQ6V0cio7vSqS8UoG/Chat?node-id=18729%3A63242

The way we display pinned messages once clicked is the same:

@gravityblast @bitgamma @guylouis clarified with @errorists and left a note in the task:
From a user profile, you always see the message pinned your one to one chat with them, regardless of where you access it from.
Left a note in the task as well.

@errorists @cammellos
rules for pining are clear. What about unpinning though ? which of the two following logic are we doing:
i/ an admin (group chat, community) or participant (1-1 chat) can only unpin his own pinned messages
ii/ an admin (group chat, community) or participant (1-1 chat) can unpin pinned messages from other admin or the other participant (1-1 chat)

[errorists]

ii/ an admin (group chat, community) or participant (1-1 chat) can unpin pinned messages from other admin or the other participant (1-1 chat)

ii is the correct way to go considering i may end up with orphaned messages as the person who pinned their message may no longer be in the chat to remove them

@gravityblast
I guess it would be helpful to mention here the go issue/pr ongoing for this feature

[gravityblast]

yes it's this one:

status-im/status-go#2180

My suggestions follow:

Need to add a "Note to self" (similar to signal) or a "saved" (telegram). This would act as a place to both:

1. Chat with yourself and
2. Forward messages to in order to save them.

Both telegram and signal do the same thing, just using a different name (Note to self vs saved).

Communities and Group Chats:

1. pinned and bookmarked messages should be stickied to the top of the chat as a header for all users. 1.1 Stacked if more than one pin.
2. ability to set a pinned message without typing it in chat. "Create new pin" option. Good for help desks, parents etc.
3. ability to forward a message
4. ability to save a message (automate forwarding to your "Note to self" aka "saved" chat)

1+2. Pinned and bookmarked messages should be accessible from the group / community chat info page.

3+4. Forwarded and saved messages should be stored in your "saved" chat. They should link back their position in the originating chat (if it still exist). If the original message or chat does not exist, the saved message should not be affected.

Pin and save control:

1. only creator & admins can pin
2. creator can remove any pin
3. admins can only remove their own pins
4. regular users are not offered 📌 , but "bookmark" 🔖 instead.
5. admins and creators are also offered bookmark.
   Bookmark acts the same as pin but only shows for you.
6. anyone can save / forward.

1:1 Chats

1. pinned messages with should be stickied to the top of the chat as a header for both parties. 1.1 should explain to user that a pin will appear for both parties and offer save and bookmark.
2. ability to set a pinned message without typing it in chat. "Create new pin" option. Good for help desks, parents etc.

Remove reply from the tooltip and replace with swipe to reply.

Completing this requires

• ability to edit and delete messages
• ability to forward messages
• local (encrypted) backups
• a (solo) chat to forward [save] messages to
• pins should disrespect the "restore" timeframe / delete timeframe. I'm not sure if message history is ever restored p2p (?) Or server only?

1. Users who have nodes disabled should restore chat history from active participants.
   1.1 option to enable / disabke "seed history to groups and communities" options for timeframes and text/text+media
2. Pins should always be seeded p2p.

Apologies for the book 😅
