Great App.

Works great for me. I see the views in the other comments but I think it is fine how it is. Does everything I need and more. The only thing I would add is the common data sheets idea.

The content is fine. Just a handy version of content you can find online. It crashes a lot though. I’ll give it 3 stars when it stops crashing.
