The D5 interface is available in Spanish, and the translation is complete. But the Asset Library is still in English: category names (Nature, Flowering Tree, Broadleaf, Conifer…), asset names, tags and search all stay in English regardless of the interface language.
The library data only carries two languages per item (Chinese and English), so there is nothing users can do on their side.
Request: add Spanish (and ideally the other interface languages) to the library categories, asset names and tags, and let the search box accept queries in the interface language. Spanish-speaking users have to guess the English word for every plant or object they look for, which slows down the workflow a lot.
