Hi! First post here. I've been searching all over the web for something like this: A text editor that allows you to load several custom dictionaries, or word lists, for its spell checker. It doesn't matter if it's Mac or Windows, as I use Bootcamp. My goal is to write content for Spanish language learners. For this, I plan to use some high-frequency word lists I have, so it would be fantastic if the word editor could warn me when I'm using words outside of the list, for example, highlighting or underlining words outside the list. I'll be using several different lists for different levels of language learners: One list with the top 1K words, another with the top 2K words, and so on. Thank you for your help!
