What a neat coincidence! Just a couple days ago, I was wishing something like this existed!

Thanks!

Would having it open a JAR from a web URL be possible in a future version?

it's possible, but what is the use case?

Say my Gradle or Maven build fails. The error message in the console might produce a clickable link to the problem artifact at https://repo.maven.apache.org/maven2/org/example/…

Say I expected a class or interface to exist in org.example:foo:1.10.0, for example. I could copy the https://repo.maven.apache.org/maven2/org/example/1.10.0/foo.... URL and paste it into your tool and see at a glance if it has what I'm looking for or not.

Also, sometimes I might like to see if an artifact is a Multi-Release JAR. Or see if it contains a `module-info.class` or a `META-INF/service/…` entry, for example.

It would be convenient if I didn't have to download it and `jar -xvf` it or whatever.

Makes sense, will look into it

Hey! Look at me! I'm vibe coding! Haha!

I send out some wishful thinking vibes and my idea magically gets coded :)

Thanks, brother!

Great job!
