Menu:  Tools --> Library --> Install library

This tool allows you to easily install a library into the default library location rather than searching around for the installed tool location path.

A file browser is displayed for selecting the new library.  When selected the library will be installed in the default library location.  You can only install a library with a different name to those already there.

Note to reset the library to point at the default location hit the button "Default library path" in the library editor dialog (see Library)
