Red Underline Spelling Errors

I was wondering if it'd be at all possible to implement a spell check system. There have been many times where I write something in my score (whether it be rehearsal notes or staff text) and I go through formatting and exporting to PDF only for me to catch a spelling error that I've made!
It'd work much like how Google Docs' version works where if you have a spelling mistake (or perceived mistake) it gets underlined in that zig zag red line. You can right click to either Ignore, add to dictionary etc.
Let me know your thoughts and whether this is practical or not.
