Proper support for hiding items that you don't want to see. (WIP)
Syncing recipes from server to client, meaning servers running custom recipes can nicely do so without additional client mods. (Requires AMI on server)
Overhauled tooltip rendering.
Tooltips are the last thing rendered, meaning you can queue a tooltip at any point, and it should render, regardless of the current GUI (if any at all).
Tooltips are screen edge aware, unlike vanilla tooltips.
They can render modern formatting codes (italics, bold, etc).
They can render itemstacks, dividers, and even images.
Customisation and extension API coming soon:tm:.
A rarities system.
This does nothing without a mod that adds them to items.
Can have fancy formatting, header colours, and icons.
Drawbacks compared to HMI-fabric:
You need StationAPI regardless of if you want it or not. (Will be worked on, but you will lose everything aside from recipe-related features)
Features over every other inventory editor:
Multiplayer NBT and metadata giving. (Requires AMI on server)
Multiplayer healing. (Requires AMI on server)
Multiplayer day/night.
Recipe viewing.
Features over HMI-fabric (for devs):
A sane API that allows you to almost entirely reuse your existing container and rendering code, removing the need for specialized containers and UIs.
An entirely redone tooltip rendering system which supports modern colour and formatting codes, and also supports rarities (WIP on latter.)
A ton of render helpers that make creating and editing GUIS far less painful.
An item blacklist API, which can be updated during runtime for progression-locked items, if wanted.
