Hello!
Is it possible to add a translation into Polish?

If so, I can send the translated file :D

If you translate it, probably.

if you don't know the "correct" way to do this with git:

• use the 'fork' option to create your copy of the project
• add the pl_PL.jsin language file, this can be done in the browser.
• open a pull request here so the dev can accept it or request changes, if needed

This looks good! I'll make sure to include the language file in the next update. Thanks!

This has just been released in 1.12.2! Thanks for the translation.
