You're welcome. Glad that it worked.
Another way to address the problem of the "convenient location" might be to draw symbolic links (unix) / shortcuts (win) to the subdirectory of the library within the "libraries" folder so that you access examples and documentation by going through the symbolic links / shortcuts you'd store in a location convenient to you while keeping the libraries installation simple by only having to uncompress the libraries zip packages in the "libraries" folder (aka /libraries).
For example, in the folder, keep a linking to "/libraries/controlP5/documentation" (or "/libraries/controlP5/" if you want to keep docs and examples together)so that when you want to browse the documentation, you just have to visit the folder.
Your mileage may vary but this may help keeping things organized in a manner suitable to you while minimizing work to shuffle things around.
