I do understand that is an option when using 3rd party libraries. When I am creating and using libraries at the same time, I don't want to have to update every project after something is changed. This could be done by creating symbolic links, but this can only be done using *nix systems.
Use case:
I am creating a WiiRemote library to help teach programming to some at a FIRST club at a local highschool. It is rather rough right now and I plan to clean it up soon. They are already using it for several projects, but I would like it so that they could just pull from my git repo when I add improvements.
To be honest, I use vim and scon when working with the Arduino platform. This just seemed to a nice feature to add to the IDE and I wanted to contribute to this awesome project. Maybe I should do something off the to-do list...
P.S. sorry for the long time between post, life got crazy for awhile
