It would also be nice to be able to select parts in subassemblies. Currently when you select a part in a subassembly, inventor highlights the subassembly and not the part itself. This leaves a person having to search through all the parts in the sub assembly in the model tree to find the actual one they want and be able to open it. Or having to open the subassembly and then open the part they need.
I am using inventor 2020 so just ignore this if it has been changed already. I previously used creo 4.0 and it was a really nice feature to be able to select individual parts in a large assembly rather than just the sub assemblies.
