As was already said, the More Hats mod will not get sanctioned as it exists right now. Getting it to be visible only to its user(s) might make it feasible, but I think it more likely needs some additional limitations, such as limiting the hat options to the same character only (so no bearded Sienna). Even then it’s questionable whether Robin and other reviewers think it too silly or lore- or immersion-breaking.
The bot improvements are on the edge too. They don’t change the game’s fundamentals, and in my opinion the changes (as far as I know about them) aren’t that big, but it does affect the difficulty of the game anytime one’s playing with bots (and honestly, through that takes a bit away from the co-op aspect of the game). I think them being separated to Item handling and Combat raises their chances of getting approved, but I still wouldn’t hold my breath. Bot selection does have quite a good chance of getting approved though, I think, and honestly, it’s the one I’m most anticipating. For now, though, Grim has marked in a WiP (or at least it was a couple of days ago), so I wouldn’t expect it too soon either.
If you want to increase a certain mod’s chances of getting reviewed in the next wave, go to Steam and upvote it, as Robin has said that the mods’ popularity is one basis for choosing the review order. It won’t affect the end result, but we will know sooner, at least.
More generally, Robin has talked about the second wave, so it’s very likely that at least the second set of mods will come in a bunch. How large a bunch, how soon, and how often after that I have no idea about. I think the purpose of the system is at least partially to get a somewhat steady flow to the reviewing process and mod approval, so I at least expect for the second and maybe third wave to be larger, and after that smaller sets more often. As Robin seems to be the one with most say about the mods, and as he’s the dev mostly interacting with modders, it’s almost certainly waiting until he gets back to work (and a bit after that, to catch up). My guess is, wait two or three weeks more before getting anxious about it.
