Hi halinagold,
If all you’re looking for is a better dictionary to put inside Scriv’s built-in spell check feature, then see this thread for links and tips on how to replace the default dictionary with a more robust one. (The thread is in regards to the v3 beta, but still applies to the production version of v3.)
If you try to set up the alternate dictionary and experience any challenges, let me know and I’ll try to talk you through it.
Best,
Jim
