[tlhIngan Hol] Software supporting Klingon for its GUI?

[c.buhtz at posteo.jp]

Hello together,
I am a software developer with several open source projects. One of them 
support over 40 languages, even some exotic ones. So that is why I am 
interested in that topic.

I wonder if there is "regular" software out there that support its GUI 
in Klingon. Are you aware of one?

Of course there are some games (e.g. Minecraft) or language learning 
software. But I mean usual software like LibreOffice, Firefox, ...

As Klingon language people do you check the settings of your installed 
software if it support Klingon?

Best,
Christian
