Inbreeding is actually a good tool, it helps solidify good traits and you can weed out bad recessives faster. Try using a download called breeders assistant or zooeasy. I used BA for years. The free version lets you keep track of up to 100 animals- I just had different saves for different lines.

I also wrote notes on my iPhone or iPad- no more pen and paper since it can get messed up as you found out. The speak to text feature helps me ramble off info quickly lol.
