Export multilingual settings with features I'm using features to export 10 content types, but I don't get the multilingual settings. My question is, whether this is even possible, maybe with strongarm or I'm stuck having to change those settings by hand?

I use the i18n module and want the content_type to be translatable, in the content_type edit menu i set:


Publishing Settings->Multilingual Settings-> Enable with Translation 
Multilingual Settings->Extended language options->Require language (Do not allow Language Neutral).
Yes, you can do this with Strongarm.  You'll want to add all the variables that are prefixed i18n_, language_, and locale_.
