I'm looking over the feature page, here -
https://valheim.plus/features
Quite a log of configurables, which the game is definitely lacking otherwise in present form.
It seems like nearly everything under "Player Modifications" is just meant to make the game easier - I wouldn't recommend changing any of those, with the possible exception of the shared map, if people want it, and allowing view switching.
The items under "Building" feel much more like QOL upgrades, and I'd be in favor of most of those being allowed. I wouldn't want to disable structural integrity, but the ABM and AEM, as well as rotation options, would be splendid.
For "Crafting and Production" there's a mix. I wouldn't modify the speeds or capacities, but I can see how things like "craft from chest" would be nice.
The "Server Modifications" element is obviously nice, though I don't know how many we'd need at the moment. Definitely keep the password. Slots we can see if we need - presently we do have a number of players, which is nice. I'm not aware of hitting 10 simultaneous yet - I want to say 7 or 8 though, perhaps?
Upshot, I'd be quite willing to give it a try, so long as we're not using it for things like reducing stamina consumption or modifying game balance.
