So... yeah. My wife's idea actually. A tool that you can load seeds into the way bait gets put onto fishing rod. Then the seeder would be upgradeable as the hoe and watering can are, eventually letting you seed two 3x3 sections of field at once. Wonder how hard to mod this would be.
Yeah, anything like this will have to wait for FarmHand, SMAPI just doesnt give us modders the ability to dive THAT deep into the code
I like this idea. It could be similar how a Golden water can works. Or iridium if you have a 200+ square wheat field
