Collaber

www.collaber.com/help gives an extensive site map to all the help topics.

Currently the left margin shows access to the topic of "Workspaces". That discussion might be more complete if a graphic showing a sample default complete workspace were shown. Visual redundancy helps understanding.

Show Tool list panel, Members, Chat, General Info, Common Tasks, and the top Menu bar.

The rest of the discussion already shows specifics about the sections.
