I noticed that Japanese doesn't have a word page listing what words you have covered and when; like what they have for the German section. Is it known why and if this will change?
Step 1. Switch to German course.
Step 2. Click "Discussion".
Step 3. Duplicate tab. (So you now have two web browser tabs, both of which on the German course and both viewing the Discussion page.)
Step 4. Current tab: Switch to Japanese course. (Can close this tab once it loads.)
Step 5. Other tab: Click "Words".
