One pet peeve that I have with the SOLIDWORKS Feature Manager, is the need to scroll back in order to see long component names inside an assembly.
The culprits behind this are Display and Configuration names of a component. I could expand the Feature Manager in order to display all of the components information, but this takes up too much screen real estate.
What I prefer to do, is set the Feature Manager Tree Display, to not show Display and Configuration names.
I do not always need to see the Display and Configuration names and I can easily display these later if I wish. To remove the Display and Configuration names from the Feature Manager, right-click the Assembly in the Feature Manager > Pick Tree Display > and just Show the Component Names, and uncheck the other options as shown in the figure below:
To retain these settings I then save my blank assembly as an assembly template.
