1: A button or option to flip a vehicle over when it is flipped. being stuck in certain spots with a flipped vehicle causes tons of problems.
2: stability on the bridge. when crossing the bridge, there is a chance that your vehicle will glitch and fling your stuff in the water.
3: a better sander, that saws linked wood into one piece, like the hand saw. the ability to sand wood like this makes the handsaw better than the more expensive sander.
4: a bank system to store money. save your money by putting it in the bank, so you can set limits and not go over spending amounts.
5. bug catching. get a net and hunt bugs, spawning an random places on the map. sometimes, rare bugs will appear, granting more money than a normal one. upon catching, it will be placed in a small, movable container.
6. weather. some days, the weather will change. in these different events, different things will spawn. for example, on a windy day, malachite spawns. on a windy night, turquoise. on a sunny day, tiger's eye. on a clear night, moonstone. and a rainy day, aquamarine. on a rainy night, sapphire. on a snowy day, opal. snowy night, fluorite. sometimes it will storm. on these days, you get thorium, and at night, ammolite.
these are just a few suggestions. i will add more later.
