Would like Dictionary updates Rated 5 out of 5 stars

I think it's a real step forward that you can get an English dictionary for Firefox(I'm using Nightly 20.0a1) rather than suffer a dictionary in a foreign dialect. I really do value this add-on very much.
It would be really good though if it updated the word list automagically by merging the add-on list with a new one from a fairly authoritative source or pointed the user to some possible sources & allowed updates, or at the very least ***allow export & import of word lists*** this last surely would be simple to implement & might even create a community around creating & improving an English word list. Dictionary is a misnomer after all - its is just a word list NOT some kind of map or indexed list.
