Compatibility:
Compatible with BetterInventory (view image), load this mod AFTER BetterInventory in file list
Partial compatibility with Save Everything (trade/container menu only, not pipboy), load this mod AFTER Save Everything in file list
Not compatible with other mods that modify interface/pipboy_invpage.swf

Usage:
Explanation same as for Invent O Matic Pipboy (mostly copy-pasted)

• You have to modify config file: inventOmaticPipboyConfig.json (file is compatible with older version of Invent O Matic Pipboy)
• Once config is populated - open your pipboy, navigate to inventory tab and press configured hotkey.
• That's it!
  

Hotkey Notes:
You can bind multiple configs to the same hotkey, e.g. drop ammo in one config and drop junk in another
Noteworthy key codes:
F1 - F12 keys   =>   112 - 123
0 - 9 numbers   =>   48 - 57
a - z alphabetical   =>   65 - 90

Config:

debug - values are true or false, needed only if you have some issues with mod.
drop - section intended for dropping all the specified items
consume - section intended for consuming/using all the specified items

Drop section - intended for dropping all the specified items

Sample of Drop section looks like this:
"drop": {
"enabled": false,
"configs": [
{
"name": "Drop heavy ammo",
"hotkey": 116,
"matchMode": "CONTAINS",
"itemNames": ["Mini nuke", "missile", "cannonball", "40mm"],
"enabled": true,
"dropFavorite":false,
"conditionUnder": 10,
"checkCharacterName": false,
"characterName": "none",
"teenoodleTragedyProtection": {
"ignoreLegendaries": false,
"ignoreNonTradable": false,
"typesToDrop": ["AMMO"]
}
},
{
"name": "Drop all junk items",
"hotkey": 115,
"matchMode": "ALL",
"itemNames": [""],
"enabled": true,
"checkCharacterName": false,
"characterName": "none",
"teenoodleTragedyProtection": {
"typesToDrop": ["JUNK"]
}
}
]
}

enabled - turns on (true) or off (false) entire drop feature
configs - list of different configs for dropping items, there could be a bunch of drop configs, each config consists of additional options:
name - custom name of the config (it will display a message in-game, once you will press specified hotkey)
hotkey - actual button that will trigger dropping, see full list of values on the link above
matchMode - one of the values:

• "CONTAINS" - item name in pipboy should include item name in config, case-insensitive (USE WITH CAUTION: it could drop too many items, in case too generic item name)
• "STARTS" - item name in pipboy should start with item name in config, case-insensitive; e.g. prefix (USE WITH CAUTION: it could drop too many items, in case too generic item name)
• "EXACT" - item name in pipboy should exactly match item name in config, case-sensitive
• "ALL" - ignores item names and drops everything
  

itemNames - list of items, that you want to drop, e.g.
"itemNames": ["item name1", "item name 2", "etc"]
enabled - turns on (true) or off (false) entire specific drop config
dropFavorite - [Optional] override for dropping favorite items, default is false (Update 1.0.1)
conditionUnder: 1-100 - [Optional] percentage of condition under which the items with condition will be dropped (Update 1.0.2)
Note: for fusion cores pipboy shows max condition 100, but they have 500 maximum condition which is 20%. So if you want to drop fusion cores under 15%, set conditionUnder to 3, i.e. 3% of 500 which is 15. I recommend creating separate config for fusion cores and binding it to same hotkey as plasma cores.
For plasma cores it works as intended, so for conditionUnder=15, it is 15% of 500
checkCharacterName - [Optional] turns on (true) or off (false) checking if specified characterName matches character in game
characterName - [Optional] character name, will be used only if checkCharacterName is equal to true
teenoodleTragedyProtection - [Optional] specific protection config, to eliminate possibility of dropping items, that you don't want to, it consists of:

• ignoreLegendaries - turns on (true) or off (false) dropping legendary items (if all other checks are passed, e.g. by item name)
• ignoreNonTradable - turns on (true) or off (false) dropping non-tradable items (if all other checks are passed, e.g. by
  item name). Not very useful, IMO, since game marks most of the junk items as non-tradable.
• typesToDrop - array of specific item types, that should be processed for dropping, e.g.
  

  "typesToDrop": ["JUNK", "AMMO"]
In this case, mod will try to drop only items from junk and ammo categories, rest of them will be ignored.
Full list of types:
        "POWER_ARMOR"
        "WEAPON"
        "ARMOR"
        "APPAREL"
        "FOOD_WATER"
        "AID"
        "NOTES"
        "HOLO"
        "AMMO"
        "MISC"
        "MODS"
        "JUNK"



Consume section - intended for consuming all the specified items (acts the same way, as you'd clicked on item in your pipboy)

Here and everywhere in this document, by 'consume' I mean using aid/food, dressing up gear and so on. Consume works exactly the same way, as you'd clicked on item in pipboy with your mouse.

"consume": {
"enabled": true,
"configs": [
{
"name": "Uny xp armor",
"hotkey": 112,
"matchMode": "CONTAINS",
"itemNames": ["**xp"],
"enabled": true,
"onlyIfNotEquipped": true,
"checkCharacterName": false,
"characterName": "none"
},
{
"name": "XP Buffs",
"hotkey": 79,
"matchMode": "CONTAINS",
"itemNames": ["Brain Bombs", "Cranberry Relish", "Sweetwater Special", "Company Tea", "Live & Love 3"],
