Innovative ideas to increase interior storage capacity?
 

So probably one of only a few knocks I have on this car is the lack of storage compartments. Typically cars this size have all types of interesting storage solutions.

I was wondering if anyone has come up with some ideas?

I want to add an armrest and obviously that creates a nice little storage compartment.

I typically have a pair of sunglasses exposed in the cup holder, a pen in the glove box, and a pack of gum and my work ID in the door panel. I wish I had some more secure places to put some loose things such as a pair of headphones I keep in the car to take with me to the gym. I find it difficult to access the back seats and I have no space to put something behind the front seats.
