Recommended to use 'Configuration\Reset all configuration...' after installing (to reload the new presets) (*). You will lose any user configured entry on the process (make a backup of the properties panel if needed).
Shift + L. Click on menu button allows to switch some entries functionality. Individual tools or entire submenus may be disabled/enabled. When all entries from a tool are disabled, the entire script files associated are omitted at loading.
See changelog.
(*) Probably many people after updating the scripts in the latest releases are missing presets changes due to not doing that!
