Honestly I agree, I love how much in this game is already there and they're one of the few dev teams I know of I can be confident given time they will keep going and get there. They seem pretty bent as is on making sure exploration is fun and rewarding. I would adore something more than Horsetail and bandages. With VS having just a bit of that video game aspect to it, I could see a lot of fun things to be had with more advanced creation of medicine with maybe the distillery, especially with the new cooking pot changes, and the ups and downs of things like numbing compounds.
Also more travel options sound really cool, I've been trying Feverstone's Horses and Joy of Sailing recently and am just nearing actually befriending a horse and making a proper boat, didn't fully understand the newer landcover options in worldgen and am apparently playing on islands, which while really fun, I've certainly been thinking about travel a lot.
