Currently, each channel is related to a space etc which is fine but the main channel which is created by default the company adds everyone in it who are users of any permission in ClickUp with no posting restrictions. It would be good to be able to decide on the default channels that will have access and restrict permissions on what users can do in those channels. This won't apply to all channels as the permissions will already add some restrictions but is more for the company channels that everyone has access too. It may be that you work with 3rd parties who access occasionally and there is no requirement for them to view or post in the company default channel.
