Tier 4 since summer and there were several announcements - what is the current status of the roadmap?

- Member in workspace: will it be possible to limit credits?
- Directly inviting a new team member; currently, the account must already exist and there is no email ("please create a new account").
- Collaborating as a team in a chat (not sharing and attend, but real collaboration).
- What about moving a chat from one workspace to another?
