Thanks for the snake belt site, I keep pinching my fingers with the plastic release system that on my present belt so I have tended to look for other secure designs, but they all all seem to be the same these days.
My suggestion for tent 'windows' comes about because of my 2015 run in with 5 assertive pigs that tried to get in my tent with me. My present tent has four 9" x 5" clear windows, (I had them specially done two years ago), two at the front, two at the rear, they are only three inches from the ground, I don't have to sit up to look out and they have served me well, especially when I'm wild camping. If a cow or sheep, etc decides to wander by I can make out their shape without having to open my tent and no longer just have to rely on sound to guide me. They also act as prompters about daylight which I personally find useful, at dawn I just like to get up, pack and go.
Another little idea that I would find useful, a small hard piece of plastic designed to fit comfortably in the palm of my hand, just to push tent pins into the soil, especially for when the ground is hard and dry. I'm sure it exists already but I've never seen one.
