Regularly when typing compound words like doesnt and couldnt I leave out the apostrophe.  When I’m reviewing my email before sending, it is underlined in red.  In most applications, when I right click, it offers the most likely suggestion.  In front’s case, it does not.  It suggested “couldn’t’ve” and did not suggest “couldn’t”.  Not sure what spellcheck API y’all are using or if it’s something y’all developed, but the suggestions are not ideal. 

While typing this I accidentally typed “msot” instead of “most” and it did not offer “most” as a suggestion.  

My suggestion is to update the spellcheck suggestions.
