Sometimes I want to create a group with the same or similar set of users as the current group to discuss a different subject without flooding the original group. Creating a new group and adding all the same users or creating a new empty group and sending a QR code to the original group then waiting for everyone to join is not convenient. It would be nice to be able to use existing group as a blueprint: clicking the “Clone chat” in the group profile should open the group creation menu with the members pre-filled with the members of existing chat, but the ability to modify the member list (removing/adding some) prior to group creation.
Maybe unify this with existing “New group or subject” option, because this option available for 1:1 chats does exactly the same, but is limited to 1:1 chats only.
