Deepin should be great in chinese but I don't understand chinease, is acceptable in English but for a long time is not evolving in Portuguese, I'm a Portuguese from Portugal and I can help translating and make Deeping great in Portuguese.
I think Deepin's feedback is not very selective, and is more valuable quantity instead of quality. I've made many feedbacks to improve deepin and I don't feel I'm listened.
Start adding back Volume and Brightness bars on Settings menu like it was in 15.7.

Please contact me if you want to improove Deepin in Portuguese.
