I'm just learning the features included. So far I'm finding this program very helpful in terms of working in Smartsheet. Customer service is fantastic! Use the free trial to check it out. It's the perfect companion to Smartsheet!

This is a super useful extension for those that work with Smartsheet a lot. It will start to pay off more and more if you're making complex solutions, or if you're maintaining a large amount of sheets with many users. So far, the most useful parts for me were hide/unhide and the automation/conditional formatting copy/paste buttons. However if you're a developer, you'll love the easy access info sheets with all kinds of IDs, and if you're making text heavy content, you'll appreciate the spell checker. As a huge plus on the personal level, the developer of the app was responsive and helpful when I had a small issue. Definitely worth the small investment.
