I'm looking in to options for things like the pillars, although you should be able to snap a pillar on top of a pillar to fit any ceiling height.

The large forge should take the same fuel as ARK's standard forge (not the industrial one), and shouldn't even allow gas, unless you mean something else?

As for 3, I assume you mean the gaps around window openings? The windows and doors are based off ARK's (stone I think it was), so just like ARK's, they don't fit properly in all wall types. Or maybe you're mixing up the Full/Extended windows with a non extended window frames (or vice versa). Can you give me an example of which window/door and what wall you're snapping to? The gaps that ARK's own windows have on non matching wall types can probably be improved for my windows and doors, but it would take some work.

1. Try to get in touch with the s + modder. (Dynamic Piller)
2. It is a shame that the forge cannot operate with electricity. (Generator)
3. If you put the door in Large Windows and Door Frames, they won't snap into the door properly.
4. The time does not matter as long as it works properly in the end. (Perfect)

Then for the structures and attitudes.
1. Please create a GameData protocol. (Structures Plus.gamedata)

Example:

{
"Application": "ark",
"Version": "1.2.0",
"Created": "2021-05-28T00: 00: 00.0000000Z",
"Creatures": [],
"Engrams": [
{
"Level": 22,
"Points": 0,
"IsTekGram": false,
"ClassName": "EngramEntry_LeashTek_C",
"Description": "S + Dino Leash",
"Mod": "Structures Plus (S +)"
},
{
"Level": 100,
"Points": 0,
"IsTekGram": false,
"ClassName": "EngramEntry_AutoCrafter_C",
"Description": "S + Auto Crafter",
"Mod": "Structures Plus (S +)"
}
],
"MapSpawners": [],
"SupplyCrates": [],
"Inventories": [],
"GameMaps": [],
"Mods": []
}

2. Create GameUserSetting.INI protocol !!!

Example:

[StructuresPlus]
AdditionalSupportDistanceInFoundations = 10
AdvTransferItemBlacklist =
AlarmPlateTribeLimit = 0
AllowAdminToDemoAnyTribeWithDemoGun = false
AllowCatalyzerOutOfElement = false
AllowCropPlotStacking = false
AllowDynamicPillarNonFoundationSupport = True
AllowGrindingMissionRewards = false
AllowIntakeToPlaceWithoutWater = true
AllowInterDynamicPillarSupport = True
AllowMakingWeaponsAndArmorBPs = false
AllowMultiToolNeuterAll = false
AllowPersonalTeleporterInBossArena = false

I probably can make the forge operate with electricity, either by using fuel items if there's no power (like S+), or making it an option in the structure menu.

I do have GameUserSetting.INI settings for changing storage slot sizes (not all of them have been updated to use it until the next update though), and I plan on adding more, I've just been busy working on other parts.
