The introduction Jumbotron keeps coming back when the page is reloaded. This is okay at the moment since everyone should see what it looks like, but in the future the dismissal should be persisted between page loads.

The way GitHub OAuth authentication is done doesn't feel right. It works, but both the code and the flow could be improved.

Some projects (like reactphp/react) can not be starred and causes this error to be thrown:

Uncaught (in promise) Error: GraphQL error: Although you appear to have the correct authorization credentials,
the `reactphp` organization has enabled OAuth App access restrictions, meaning that data
access to third-parties is limited. For more information on these restrictions, including
how to whitelist this app, visit

If possible, star/unstar button could be disabled for these projects. Either way, a proper error message should be displayed when a repo can not be starred.

CRA is limiting. For example flow-typed install -s does not detect CRA-boxed Jest so we need to put libdefs in manually to get proper type coverage in tests.

Ejecting would also create more possibilities like SSR.

A logo for NavBar and favicon would be nice.

• There should be a way to know if a user is logged in without opening the hamburger menu.
• Hamburger menu seems unnecessary. If there is an easy way to make an icon-only menu that could be nice.
