Problems to Solve for Shopify Merchants?

I was planning to build a shopify app as a way to get my entrance into the world of entrepreneurship. I was doing some research and came up with 5 ideas and decided to write a piece on it [1]

Any shopify merchants who can give me feedback on it? Are you currently using another mechanism for solving any of these problems? Are they even real problems in your opinion?

Would love to have a discussion on some pain points in merchants lives; as I want to build a pain killer and not a vitamin app.
