Problem / Use Case
meshPanel uses tabs in many places to switch between related views (e.g. in the Platform Builder under Building Blocks). The left sidebar is underutilized in these areas and gives no indication of what sub-views are available, requiring an extra click to discover and switch between them.
Proposed Solution
Expose tabs as dedicated sub-items in the sidebar wherever tabs are used today. This allows users to navigate directly to any sub-view in one click and get a clearer overview of available views at a glance. For example, in the Platform Builder the "Building Block Definitions" and "Building Blocks" tabs would appear as sub-items under "Building Blocks" in the sidebar.
