Thank you! I will add that to the upcoming version.

Pardon my ignorance, but how is it different from #352 ?

Hi.
In the file above, this line "mup_max_variants_help": "Cada vídeo vem em formatos diferentes. Mostramos primeiro a melhor versão e também alguns formatos alternativos (vaiantes).", has a wrong word "(vaiantes)". It should be the word "(variantes)".
I don't have the original file to check, but vaiantes is to a valid word in Brazilian Portuguese.
Other phrases and words in the file are correct.
