Board specific libs in "Examples for any board" #6884
Description
A fresh install of the Arduino IDE populates the Examples menu section called "Examples for any board" with several board-specific libraries. Currently Adafruit Circuit Playground, AudioZero, Esplora, Robot Control and Robot Motor are narrowly focused to only specific boards. Several others are networking libs that theoretically could work on different boards, but in practice only work with Yun. Maybe these should be moved to platform folders? At the very least, having so many board-specific libs in "Examples for any board" hardly seems like a good user experience...
