If you translate you're itemtype descriptions then the translated strings are just listed one after the other in the description field for display in the Item types administration table.
I think it would be considerably more readable if we used the current translation in display there with perhaps the addition of a (X of Y translations complete) note to highlight the number of translations currently undertaken (where X is the number of translations completed and Y is the number of languages installed/enabled on the koha installation)
I don't know how easy this would be to implement, but what about this: The currently selected language's translation displays by default. If there is no translation for the currently selected language, it displays another (Next available, or default to English?) and links to the translation widget.
This is how it looks:

Spanish selected: https://snag.gy/FxfgPK.jpg
If this was to be changed, I'd suggest that there is still an easy way to see where you might have missed adding a translation in the table. I am not unhappy about the current display. Maybe the current could show in a separate column to the translations?
