Like I wrote in a comment yesterday, I did find some bugs around the localization feature. I managed to get it fully working and published version 1.7.0 with the updates.
I also run some tests combining Visustella's Message Core and DK Tools Localization plugins, and have confirmed that the wordwrap feature works perfectly with this combination of plugins.
Be sure to check the "Compatibility Warnings" inside the plugin help section, as I've added some important notes on how things must be configured for proper compatibility with DK Localization plugin.
It took a while for me to get time to look into this, but I hope it was not too late! =)
