Do you have a rough estimate for the needed time to translate to one language?
The SUbD UI has 150 little items so not a big deal! 3 hours if you are not speed!
A gas Engine UI like 3DCoat + Hint Tips is something like many more 5 000 item (with big item ones)
That is an another story!
For the SUbD site
+ Quad Tools + Manuals that is also another story!
But very funny to make!
