Low priority of course. Feel free to postpone, ignore, or close this issue, but this only adds one thing (technically two items)
Information:
- Purpose for adding: Saves time when switching between many different tools. This is a convenience mod that takes up a baubles slot.
- In all stages you have multiple vanilla and modded tools/wrenches/gadgets so this would save searching through your inventory and switching things to your hotbar
- Mod author does comment on curse comments and issues, last post Feb of this year
- Config file to tweak various properties, also includes whitelist/blacklist if needed
- belt does not allow stackable items which is how it restricts to tools

I have been using this in my single player world for months so feel free to ask me any questions
Possible Risks:
- I have not personally tested it in multiplayer or with a ton of modded items (but then again there are no bugs reported for that)
- it uses a keybinding which might conflict with some players existing settings
- will take time to stage and customize recipes (optional).
