If I consider making this change with my library's collection codes the tabs would become unreasonably long. It's already a little strange, the tabs wrapping onto multiple lines.

I don't know how common that is among libraries. I'm inclined to say that anyone who is administering Koha should know what all the collection codes mean anyway. Perhaps we could add a title attribute to the tabs which shows the ccode description?

Hm, I think you are right that it will make the page less readable if we switch to using the descriptions. My impression was that we aim to always use the description and leave the codes to the database, maybe we could say that administration is excluded here.

Maybe we could add the full descriptions as a title/tooltip?

I think this is a good idea but I'm not sure how to get the right data to the template. Right now all there is to work with is code, and I'm assuming that it would be more efficient to fetch the descriptions in the script.

Correct me if I'm wrong and I'll use the template plugin.
