88a8f0c i'm not adding any new translation, but fixing those who are in the en.json file but not implemented on the code

There's an issue with some dropdowns that have translations declared on a js object, some aren't replaced with translations

After investigating a little, it seems the issue is caused by the language being loaded after getting these strings. So, possible solutions:

• Crappy way: put these vars at the bottom of the script
• Good way: update this vars on initLanguage()

Will try the good way lol

Anyways, I think it would be better to create another PR to fix all the missing translations, so I'll leave this conclusions there.

Still, I'll upload the temp solution to this issue lol

The strings are 100% translated, Spanish is now in the review stage

Sorry for the inactivity.
First of all, after another test (ignoring all the big strings that make the UI a bit ugly, and missing translations) everything seems fine and correctly translated to Spanish.

@BlueOvi kindly please un-draft the pr pls :)

@Natsumi-sama whenever you can please review this temporary solution, and if needed, propose or edit the file with a better one.

EDIT: This is a MVP tho as it remains a lot of work to make the Spanish language look good in the UI

I'll merge this into the nightly build, widen any columns that are overflowing by a few characters and check over that temporary solution. Feel free to make another PR after for touch ups or extra translations.
