Oh, I make LIBERAL use of the Memorize/Restore pose function in DS! LOL!! I am such an off-the-cuff artist, that I frequently am adding and removing things all the way through the scene until I get the "final setup" that I'm going to render, and if anyone thinks I'm going to manually re-pose every finger, toe, or joint on my characters just to load in a piece of jewelry, they're smoking something and not sharing it!
I love that little trick.
I sometimes also make use of the Memorize Figure Shape/Restore Figure Shape as well, if what I'm doing is changing a hair object out
(and I NEVER conform my hairs, they always get parented to the heads), or adding in things like a headband or crown or such where my morphed figure's shape overly complicates matters. You can do both at once - memorize the shape, then have it memorize the pose, then set both to zero, make your changes, and restore each one and you're off and running again.
I love that little function, it saves SO many headaches and helps keep our swear jar a little less full.
