A Chrome extension that replaces occurrences of the A word (not that one, the one that's overused by Californians to describe things that are good) with a much better old-fashioned synonym. Look, maybe a picture would help:
In Chrome, choose Window > Extensions. Drag thats-marvellous.crx into the page that appears.
The extension prefers British to American English. I should make that optional.
If I hadn't had cloud-to-clown to crib from this probably wouldn't have happened.
