Thanks for bringing back translations!
I'm so glad the translations aren't limited anymore! One of my favorite features.
Although I'm still not sure about when something is "100%" translated, especially since I'd rather translate everything I can anyway for practice.
Before, when I'd go to translate something, it would tell me that everything was 100% translated and I could rate sentences; now I've been able to actually translate sentences a few times.
If you go to the Translations section and then select the "Recently Added" tab you should be able to find documents that haven't been mostly translated. I prefer translating a whole document rather than snippets and using Recently Added makes a big difference.
