I'm looking to make a modpack, and it's going to be HQM based.
However, I need to be able to tweak recipes and the way the world looks, anyone have any mods?
For recipes, MineTweaker's your best bet.
There was also a mod that "generated" a save, which is quite useful for packs like Crash Landing.
MineTweaker only has two builds from Sep 2015 that go up to 1.8.7 and 1.8.8, so not all that attractive for use in 1.8.9. You could consider CraftTweaker instead.
