Advanced
Debug Mode
Is enabled when Blender is started from command line with --debug-value 1 argument (or any non zero value) or you can set this at runtime by searching for Debug Menu and setting value in popup menu.
If Debug Mode is enabled, PCV will log more info to a console (terminal window, not Blender Info panel). In some cases even operation progress. PCV panels will also get several extra buttons to force shader rebuilding, debug options, some more panels with runtime info etc.
PCV preferences will also show more utility operators for pip command, listing installed packages, install package prompt, uninstall all packages from user site-packages directory etc. These operators are hidden from Blender Search Function to prevent accidental running. Can be only run from button in preferences.
