Do you name your boxes?

[PinkIceFox]

I have at least one box labeled as 'Friends' where I keep pokemon I've used the most (this one was mainly adopted from when I do Nuzlocke challenges).

The rest of my boxes are sorted by type and named as such. Though I tend to combine types into one box if there aren't too many of that type. I also change the backgrounds to match the name as best I can. In games with wonder trade options I also tend to have a box where I keep 'trade fodder' so I can slap a decent item on them and give presents to other trainers.

In Nuzlockes I also have a box that's usually named after the graveyard area of the pokemon region (like in Kanto and Johto it owuld be Pokemon Tower or something). I don't release the pokemon mostly so I can keep track of who I've lost and where I caught them.

I don't think I've ever done this outside of that one Nuzlocke I called off. Normally I put any important Pokémon in the last available box and that's always been enough for me to find them.
