+1Here's one that is likely a me problem but I've always thought would be cool.
Telescoping wheels that can be individually adjusted. Our patio slate is fairly uneven, especially after rough winters. I can't tell you how much time I've spent trying to keep my grills and smoker level.
If we (I) could raise/lower the wheel height incrementally it would be a game changer.
