I think that Hebrew/Arabic (or any other right to left language) support will be nice. I think that QT can handle it nicely (According to the examples, no other GUI changes needs to be done in order to support this feature)
If it doesn’t require much of re-coding then yes. I can imagine Chinese, Japanese, Korean etc. If we could support the right to left easily why not. (low hanging fruit).
