Do you have a Chrome extension use case?

Would you, as a non-tech person, build a Chrome extension for your own needs if you knew how to do it?

I wonder how often it pops up in your mind that would be great to have an extension to do this for me, but:

1️⃣ There are no such extensions (or you can't find them).

2️⃣ You do not trust third-party extensions for security & privacy reasons.

3️⃣ Existing extensions are not exactly doing what you need.

Please, comment if this is your case.
