AnimDesign Beta?

I just have a few questions about it.

1.How do I load my custom animations into a lootfest world?

2.If I edit the stock animations for the character / skeleton etc... will it affect them in game?

.

It would be usefull if you could use the animdesign thingie to make animated blocks and/or mobs and then have it inserted into a wave e.g nukeclear zombie: destroys world if left alone for 20 seconds only 1 per wave and only spawns after wave 50 (can be disabled by removing terrain damage) or making NPC's which wander and randomly build themselves houses in the wilderness also making spear lvl2 pack a bit better than making it so you can only carry one more spear and the spears doing same damage as the sword if spears were at lvl 1 3 to hold at max but insta kill any zombie the hit with a throwing distance of 8 voxel block things and at lvl 2 making max carry 5 and travel distance 16 voxels
