Is there a way to translate Sanity Studio?

I'm trying to use Sanity for the first times, as it looked a good headless CMS approach.
But I didn't find any ways to change the interface language. Does anyone know how to do that?

Is there a framework similar to the EditorKit, in the JavaFX?

Is anyone aware of the similar framework based on JavaFX?
I was looking through the JavaFX API. Searched the web for third-party library that offers similar functionality, but failed to find anything remotely similar to the EditorKit...
There is HTMLEditor for HTML editing, if needed. By default JFX doesn't provide anything similar.
RFE : javafx-jira.kenai.com/browse/RT-30318
Question from developer : "what is missing from what we offer presently?" you (and anybody who wants) can comment on it in the issue. It is closed as not an issue for now, as, there not enough info about needs of such extensions.

Is it Appstore save to subclass a UINavigationController?

In different threads I read that it is not recommended to subclass an UINavigationController.
But is it AppStore save if I would do it? Has anyone any experience with this?
I have published a subclass of navigation controller that does exactly this.
Check out at: https://github.com/vitorll/CustomNavigationController
With these class I already published three apps in the appstore. And I know at least one friend that have used it in another 2 apps already approved by Apple.
If you need more help, let me know.
