⚠️ Common Mistakes

Installing without checking requirements

👍 Pros

Huge community trust (4,944 endorsements) — this is a must-have for serious modders.
Actively maintained (updated June 2026) — you know it works with current setups.
Backed by a team of legendary modders — quality is basically guaranteed.

👎 Cons

No detailed feature list in the description — you'll have to dig into the docs to see what's new.
Utility mod, not a gameplay addition — if you're not modding, this does nothing for you.
Requires you to be comfortable with the GECK — not for casual players.
