I uploaded a custom snapshot of library USB Host Shield 2.0 in order to test/develop support for the Arduino 101 board. That worked OK (although it would have been niftier if the Web IDE had allowed me to fork/modify the library directly in the editor..).
BUT now that my changes have been released in version 1.3.0 of the official lib, I can't delete the custom lib to save space, and, even worse, it seems that I am forced to use my custom lib instead of the official lib.
When I try to delete the custom lib, a yellow popup appears to alert me that there was an error deleting it.
Even if I select the latest version of the official lib, the custom lib is still used:
