On the current prototype:

• I tap "show more languages"
• I scroll a bit to find my language, eg French
• I tap on French to select it
• then the name of my language seem to disappear from the list! (actually it's gone checked on the top of the list)

I find this confusing for the user, the feeling is "I tap = it disappears" which is probably not the feeling we want to give.

Note that when I start typing a language, the behaviour is better: the language "disappears" from its position in the list, but I see that it appeared checked at the top. Maybe this behaviour should be copied for the case where I don't use the search field.
