What tool would be useful for you but doesn't exist?

Is there anything in particular that you believe would bring you some value, while either doing SC development or just interacting with Ethereum network, that does not exist?

I'm doing some research on the painpoints that people from Ethereum community are facing. And after identifying them, I would like to try to solve some.

I'm very passionate about creating products that could bring value to others. It can be anything from an open-source tool to a service in form of a startup product.

I'd love to hear your thoughts!
