I've made a few UMods for my own use, and I thought others might want some of them too.
If you aren't aware, UMods are mods that apply to the entire game, not just custom dungeons.

Included in the collection:
SecretButtonDetector: Displays a message whenever the party moves onto a tile containing a secret button. No more tedious searching of every single wall!

SecretButtonAndItemsDetector: Like SecretButtonDetector, but also displays a bag in the lower left whenever there is an item on the current tile. No tedious searching for ground items either (especially in foliage)!

ToadNoSwiping: Removes the swamp toad's steal attack, so they can't take your items. Only works on new toads, so a new game is preferred unless you have the technical skill to respawn them all via console.

CooldownRateBuffBugfix: Fixes a bug with speed-boosting traits that makes them not work with all actions. Notably, spellcasting cooldowns aren't affected.

HerbsWeighNothing: Makes herbs weigh nothing. This technically only applies to new herb items, but it's very easy to convert old ones into new ones: just drop the old ones onto a new stack. Shiftclicking out one item creates a new stack to do this with.

Download: Putting two links since I'm not sure if Steam will eat either of them.

^Click the download link in the upper right, then click "continue with download".

Installation:
1. UMods require using the "nutcracker" beta version, accessed with the code "ggllooeegggg" (input in the Beta tab of the game's properties window on Steam).
2. Start the game up then close it.
3. Go into your game save data folder (Documents/Almost Human/Legend of Grimrock 2), and there should be a Mods folder and a file called mods.cfg.
Place the mods (.lua files) into the Mods folder.
4. Edit the mods.cfg to add all the mods you want to use. Here's an example:
mods = {
"CooldownRateBuffBugfix.lua",
"HerbsWeighNothing.lua",
"ToadNoSwiping.lua",
"SecretButtonAndItemsDetector.lua",
}
You can just copy that and remove the lines you don't want.
5. Done! Just start the game and they'll be active.
You can quickly test if it's working with SecretButtonAndItemsDetector; it will show a bag icon in the lower left whenever there's an item on the tile you're standing on.

You can find more UMods here, including an in-game mod manager that handles mods.cfg for you. I use the mod manager, Cooldown Clock, Sleep When Unfocused, and Editor+.
