TL;DR: Please add a direct “Copy Path” option in the Source section of Layer Properties, or at least display geodatabase paths on a single line so they can be copied in one step, and update the existing copy path button in the Map Ribbon to actually return the path.
ArcGIS Pro already makes it easy to copy a dataset path from the Catalog pane when the item is visible there, but that workflow breaks down when the user is working from the Contents pane and needs to confirm or copy the source directly from Layer Properties. In the Source section, shapefiles display the full path on a single line, but geodatabase feature classes split the database path and dataset name across separate lines, forcing the user to manually copy and reconstruct the full path in two steps. This is a small but persistent usability issue that slows down troubleshooting, scripting, documentation, and data handoff. A simple “Copy Path” button in the Source tab would solve this cleanly. At minimum, ArcGIS Pro should display the full source path for all data types in a single copyable line, not just shapefiles. The Copy Path button available in the Map ribbon menu (see attached graphic) returns values like "CIMPATH=Map/Peru_OptimalPaths.json" which is not a path useful in code. The actual path for that layer is: N:\PerLinesComp\PerLinesComp.gdb\Peru_OptimalPaths. So an adjustment of the existing copy path button would else better enable UI/UX.
