Thanks! I have just updated the live preview:

However translations aren't fully complete (3% left). They also usually need to be reviewed both by another Dutch speaker and by me, using Google translate to compare translated strings with the original ones to spot disprepancies.

Are you confident that your work is accurate - consistent with translations, typo-free and easy to understand and read for Dutch speakers?

Once translations are complete and reviewed, they can indeed be submitted in a pull request, but I usually take care of this part since I must review and test translations.

Thanks again for your help.
