Tip’s:
• I Always prefer to Copy a Kicad stock Footprint and Symbol, then paste it into my preferred folder. You can Right-Click and Rename it then.
Alternately, can Copy/Duplicate/Rename and Move it BUT, I prefer the above approach.
• When Creating a New Footprint/Symbol, 'First’ Select the desired folder to save it to, then Save (first selecting the destination Folder is what enables setting a New Name)
• Setup your Paths to point to your preferred folder
