A coding tool for Shopify devs, let me know what you think

I'm building Code Sense, a VSCode extension that will help automate the process of searching and navigating through unfamiliar codebases. The goal is to help developers like myself, who work in new codebases regularly, save time by doing a lot of this searching for you.

A bit of background, I work in the Shopify theme development space, at first for a few agencies and then for a Shopify app company, and was very regularly working on sites I had little to involvement with while they were being built. The amount of time I spent just trying to find all the files related to the feature or bug I was working on and then understanding how they all connected left me feeling "there must be a better way."

I have not launched yet, but I have a semi-working prototype and am looking to get some feedback on the idea before I invest too much time in something that might not have any demand. The business model I'm thinking of is a freemium model, which has me a little concerned because there are not a lot of paid VSCode extensions. I do plan on expanding the feature set to include more tools related to this area of the developer workflow.

My ideal customer profile (ICP) is web developers who regularly work with code they didn't initially write, especially Shopify devs, because that is the use case I'm initially building for.

My main questions are for people who at least somewhat fit the ICP are...

How frequently are you working with code that is unfamiliar? (either a codebase you didn't build or a part of a codebase you didn't build)
Do you think you would save time with a tool like this?
How likely would you be to pay something like $5/month for something like this?

Also would love any feedback on my site/landing page - https://codesense.io/
