Modora

Paradox games load mods in an order that matters, and a collection of forty mods gives you no hint about what that order should be.

The usual fix is a forum thread, a lot of dragging, and a crash on launch when two mods quietly overwrite the same file.

Modora reads a public Steam collection, resolves dependencies and known conflicts, and emits a mod order you can import straight into the launcher.

Conflicts are shown, so you can see which two mods disagree and decide which one wins.

A forty-mod collection becomes a working load order in about ten seconds, and any conflicts are named before you launch the game.
