Translation of all layers into other languages with one click

Haha, you don't want much do you! Perhaps an extension panel could do this by leveraging a web service.

I'm thinking that this may be possible with more than one click, however the devil is in the details...

1) Run script to create an array of layer names copied to the clipboard

2) Paste array into web browser or other translation tool, copy (or save into a text file)

3) Run script, paste in clipboard or read translated array and rename layers

There are numerous challenges, certainly not impossible to deal with.

Good luck!

I never heard for similar script. Try on Adobe Exchange or simply post request here on forums for such script and you may get it from someone if you are very lucky.
