I think this behavior has been introduced by PR #275 unintentionally.
Making the name flag global in the capture command requires name to be passed even in the capture list command.

I believe this should be fixed in the next release. I removed the requirement for the name flag to be required here

When building the CLI from source on my machine, I can run kubectl retina capture list without passing any flags.

From my understanding, the way to install the CLI is through Krew, which uses the a krew-index based on the latest release of Retina. The PRs I made where after the 0.0.16 release, so are not included there, but should be in 0.0.17.
