I got a few i have noticed as well, besides what you already mention (extra +1 on the terrain issue).

Better enemy AI would help a lot, even just small improvements. I am not talking about giving every enemy new moves or something intensive like that, but some pathfinding improvements are still needed. Though I have totally already noticed some improvements there across development, they still have issues like refusing to drop off a foot high ledge so they will happily just let you wail on them while they whiff over your head instead (which would also be related to the terrain combat improvements if enemies could do it to). Or a sort of common sense mechanic where the annoying little fodder enemies realize they do 0-0.2 damage and maybe decide that's just suicide if they don't wait for a few buddies. Don't make them entirely passive if you are too far ahead of them, but let them get a sort of mob mentality if you let them group up still. That way they are still annoying little pests, but aren't actively interrupting literally every action you take in the wilderness (looking at you specifically greydwarf/greyling, you are the worst offenders). Mind you that one likely would be based on a threshold of the maximum damage they could individually deal the player, so enemies that actually still are a challenge to the player or can deal a lot of damage under the right circumstances would still be exempt from this (and i imagine a few mobs might be excluded for lore reasons, like the literally brainless undead probably arent fearful or great at planning).

Ship lighting would be lovely, even if we just got to hang the new lantern on the bow of the ship or something. My game is already intensely dark (already filed a report for that a looong time ago) so I really would appreciate a bit of help seeing when i might crash into a slightly submerged rock at night. Even with the headlamp, for my game at least, i can't see past the deck. Water, of any depth, is just an inky void for me at night. Plus the light can help you find your boat if you were exploring and parked somewhere weird that maybe you forgot to mark because there happened to be a welcoming committee (totally not from personal experience/mistakes on that one, totally lol).

Though on a related note, brightness options in general would be lovely but im already a part of a few of those suggestion forums thanks to my brightness (or lack thereof) issue. [Also for any concerned, yeah i already went through troubleshooting on the forums specifically related to lighting issues in game. My best option is adjusting the brightness on my monitor or graphics card for specifically this one game, and it doesn't even work for me. I just get washed out grey instead of pitch black. At least the black doesn't hurt my eyes.]

Air Defenses. Mind you i don't mean i expect a viking to have a fighter drone or something, and we actually did get this in some capacity with the rather tempermental ballista. But the raid events and defenses are a pretty big part of the game and right now there isn't actually a lot to it. Earth walls/trenches keep out anything on ground, or you got an assortment of walls if you dont want to go that route. Roofs keep out fliers, mostly...but we don't have a lot of defenses against fliers. We get traps, spikes, moats, walls, and the ballista can cover whatever the heck it can look at (including you) but the ballista is also the only one that can really help you out with flier raids, and those darn bats can squeeze into tight spaces (like your chimney) and end up in places you never really thought you'd be fighting a mob in (like your kitchen, R.I.P. berry chest). Heck for some of these id be content if stuff like the iron bars actually let light/smoke pass through in the mechanical sense so you can actually use them to block off things like chimneys or cover your garden in case of flier raids. Especially as we get more fliers capable of raiding.
