Invention idea – transparent airplane luggage compartments

My default method of transportation when traveling to foreign countries is flying on an airplane. I only fly economy and each time I board the plane, I have to put extra effort to ensure that my carry-on luggage will be able to fit in the overhead compartments. Typically, there is just enough room for everyone’s luggage. However for the packed flights, the luggage tetris takes a bit of time to complete, with flight attendants opening and closing numerous different compartments to find a suitable spot. If it was possible to have the closed overhead compartments to be slightly transparent, then it might speed up this process. Perhaps it is not a big enough deal to worry about optimizing, but in a recent flight, I swear they spent at least five to ten minutes trying to find a spot. If people are uncomfortable with seeing the luggage during the flight, there could be a function to turn the compartments opaque.
