Torchleech is a mod manager for the game torchlight. See my torchlight review here.
With it you can browse a heck of a lot of mods. You can see the description and their official website also appears in a small mini browser window. If you want to install it, the program will download and install it for you. It also checks for conflicts.
It also has functions for quickly disabling or uninstalling mods.
I give it 5 out of 5.
Torchleech is free but donations are accepted.
