I'm trying to learn KiCAD and it seems that every 5 minutes I cannot find a component and substitute a different one (e.g. substitute lm317 for a lm338) This works all right in the schematic part but if I ever get to pcb making or testing this will obviously cause issues. Can someone give me link(s) to ALL of the libraries both for footprints and schematics. (I know about the github one but that seems to be missing stuff). Also to install the libraries all I need to do is just copy and paste the .pretty and .lib files into the libraries folder right?
EDIT: I once installed about 100 gigabytes of Cygwin dependencies so I don't really care about saving storage space/ bandwidth.
