Feel free to enter here the bugs you just found.
Diff algorithm
Very simple, needs a lot of improvement as it is far from only showing minimal differences.
Lang modification
When renaming "default" lang, it is not possible anymore to edit root page. That's because the wc_default_lang hidden configuration variable is not changed as well.
Step to take :
- when renaming lang whose value is wc_default_lang : also change wc_default_lang
- visually display the default lang
