October Novel Prep Challenge

Y'all might have already figured this out - or not, if you're not used to doing this much prep for a story.

While doing the prep with World Weavers' and now here, I've had quite a few big fixes (about characters, plot, location) reveal themselves, or new ideas creep in, that make the world work more seamlessly than it did before. But there's so much going on, I just know I'm going to forget these exciting breakthroughs! Even if I write them into my prep docs, it's still likely that I'll lose track of them. My brain is less like a sieve and more like a colander.

So, I'm dragging out my whiteboard to write them there. Does anyone else have a suggestion, besides sticky notes?
Cheers!
