Dollar bill compartment lacking

This was a replacement for a nylon wallet that I had had for over a decade, and that was a hand-me-down from my brother. These things are very durable.What I don't like about this wallet is that the dollar bill compartment is secured only on two sides, the right and the bottom sides. If I had know this I wouldn't have bought this wallet. I have since glued the left side to make the compartment more secure. I need the sides secure, because I keep papers and receipts on both sides of the compartment.On the plus side, the compartment behind the right vertical pocket has a velcro enclosure, allowing me to securely put change or keys in there. I did not have this feature on my last wallet.
