Add multi-language support, I have completed the Chinese translation #2362
Description
Describe the problem
This is a very good app. I have been using it and I think it is very useful.
But unfortunately, it does not support multiple languages. I found that it has a framework for multiple languages, but in the settings, it still cannot switch the language.
Describe the solution you'd like
I have translated this app into Chinese locally. I have completed the Chinese translation. If possible, I would like you to add multilingual options in the settings and automatically display the correct language according to the browser language. I will upload the Chinese translation to the source code at that time.
