This is a mod to control/replace the way sorting is done in-game.

Sort order is changed to follow the order defined in Auto-Sort.json. (Assuming the file doesn't exist in the first place.) (See Configuration)
The online storage tab is auto-sorted by the same rules. (This is a virtual / aggregate view of the inventories you have. This doesn't change or move the actual items, just the display order.)
Player inventory "Stack" button rearranges items, compressing/restacking and ordering by the sort rules.
Online storage "Stack" rearranges items, compressing/restacking all the inventories connected to online storage. (Again, ordering by the sort rules.)
- This also prioritizes storage containers over the drill storage, and fills the drill storage last, if there's not enough room in regular storage.
Repair Packs are further sorted so the most damage one is listed first. This is because the game uses the first entry in your inventory when repairing.

Config

The first time Volcanoids is run with this mod installed, it will create a file called Auto-Sort.json in %LOCALAPPDATA%Low\Volcanoid\Volcanoids\Mods.
This file is a simple list of the items we resort, in the order they will sort in-game.
The list entries contain both the assetId & a name. The name is for reference only. Re-arrange as needed.
Use https://jsonlint.com/ to validate edits made to the file.
If the syntax is wrong, or there's any issue loading the file, it will be ignored and a new default one will be created.
