There are literally thousands of mods for the newer Paradox games on the Steam Workshop, but we have no way in the official launcher/mod manager to detect conflicts between them and change the load order. These are two absolutely vital things when you are using a lot of mods together. I bet most mod users don't even realize that their mods are conflicting and causing problems. Amazingly, no one in the community has made an unofficial mod manager to fill this need either.
