Select coordinate systems used in project maps from Favorites when running tools from catalog view
Similar to how you can easily select one of the coordinate systems used in your map when running a GP tool in a map, show coordinate systems in use within your project's maps under Favorites when running tools from the catalog view. Right now it's just empty -- no favorites.
Can you provide more information?
Going to Catalog View > Tools > Project > Coordinate System options,
I can see both the 'Favorites' and the Layers for any open map I have in the ArcGIS Pro project.
If you would like to see favorites, add the coordinate system as a favorite.
If you want to see layers, open the map.
If you want to see all layers in all your maps for the .aprx file at this stage, I don't think that's a good idea as it'll be resource intensive for very little gain? You'll need to explain why this particular workflow is important for the idea to take off. Just add them as favorites.
