JSGME is the answer to the problem of having too many mods active at once. JSGME manages mods so only the active ones are loaded. JSGME works with any game/sim, but no better example how it works than with rFactor.

One of the best, mot underrated utilities for gamers, and its free (but he does appreciate donations).
