V5-Client/V5 ? reverse-engineered prompt

Build me a JavaScript module for the V5 client that adds a few useful in game quality of life tools and macros. I want it to feel polished and easy to use, with clear chat messages or a small GUI for turning features on and off, plus sensible defaults so it works right away.

Please make it fit the way this client is meant to be developed, so it can be reloaded quickly while testing and won’t fight with the client’s updater. Keep the code clean and organized, and if you need to check current docs or APIs, go ahead and look them up online.

I’d like the result to be something I can drop into the modules area and start using without having to understand all the internals. If there are a few reasonable feature ideas that fit this project, pick the most useful ones and wire them up in a simple, reliable way.
