I decided to start off with convenience rather than speed. That will come later.

Parcel shelf. Not all that impressed with the quality of it, but it's very useful.
Glove box organizer. Self explanatory.
Window auto-up window module. Should have come from the factory, but a pretty straight forward install. Used the "blind" method of installation. Reconnecting was challenging, but doable if you have small enough hands.

Not very exciting, but just thought I'd share.
