I am planning to add support for the IDE so that multiple library locations can be used when compiling a project. This way, libraries would be easier to track and update across multiple projects.
Reason: When the Arduino IDE is installed into /usr/share/arduino/ it is difficalt to add 3rd party libraries, if not imposible when you don't have admin.
How: Besides using the default 'arduino/libraries/' location I would also like to use '~/.arduino/libraries/'.
Any feed-back or requests?
