RE: Ghibli numbers, you can request correctly numbered slipcovers from studio canal, a few of us on here did so ..all free, they pay postage too :3
I keep the Anime Limited stuff together, looks better that way, followed by alphabetical however the Monogatari franchise is immune to this, I keep them together in order by air date.
I separate BD's & DVD's & I try to make everything level, no big boxes by standard BD's (I only have larger stuff like that from A/L so its ideal)
Honestly, I'm real fussy! it has to be that way, I cannot deal with it any other way but I have a serious issue with things being out of place or messy ..It irritates me big time so yeah.
I should really get my photos up, been a very very long time since and I've had a few clear outs since.
