JA Sensei version 2.2.0
For this new version, I've improved the "Community" area to display more clearly members' level and grade. In general it's also easier to use.
The oher big new feature is the Personal Lists management. You can create, modify, delete as many lists as you want. This concerns the Kanji and Vocabulary modules. Your lists are saved even if you upgrade JA Sensei.
At last, the new Counters module. Counting objects in Japanese is not an easy task because the Japanese language uses counters. 15 counters have been integrated currently, but much more will be added.
A few errors have been fixed. Thank to those who let me know about them.
