Project improvements

[LuisPeregrina]

@npx some improvements that I would love to see:

• Allow contributors like the three guys that have open PRs
• Add tests (we could help)
• Add icon

Hey @LuisPeregrina and everyone else who contributed!
I am really thankful for every single contribution, but somehow I kept moving this up more and more until I forgot again. I invited you as a collaborator and you can incorporate the changes!

If you need me to redeploy the extension, hit me up. I will try to make time for this soon then!

Thank you everyone!
