What would you recommend for the first open source project?

Question

JavaScript

Hello. There was a desire to make a small opensource project. And naturally the question arose of what to do. So far there are only 2 ideas:

1. a number of components that, in their total application, form a kind of desktop (tape with open applications, windows, explorer, search, etc.)
   
2. just a file viewer with the ability to display in a modal. With ambition to cover as many file types as possible
   

For the first option, the choice is between angular and react. For the second exclusively vanilla.
I wanted to ask what would be more socially useful and more developing? Maybe you can offer some other ideas (what would you like)? Thanks in advance.

Answer 3
