Replaces the sidebar workspace region with a two-tab browser: several workspace roots stay registered side by side while conversations are filed under the real working directory of each session, with a read-only resource tree that previews files in the right sidebar. Hiding is per tab, display-only and fully reversible; a resource folder or file can be copied as a path or dragged into the composer as a native reference, and @ completion covers every registered root rather than the working directory alone.
