Thanks for submitting your kubectl plugin to Krew!
One of the krew-index maintainers will review it soon. Note that the reviews for new plugin submissions may take a few days.

In the meanwhile, here are a few tips to make your plugin manifest better:

• Make sure your plugin follows the best practices.
• Eliminate redundant wording form shortDescription (it should be max 50 characters).
• Try to word wrap your description to 80-character lines (no usage examples, please).

Thanks for your patience!

What do you think about something more explanatory for these descriptions:

Short: Interactively choose get output columns

Long: This is an interactive tool to pick which resource fields you want to show in the kubectl get output.

[flavono123]

agreed. and the short one will be represented in https://krew.sigs.k8s.io/plugins/ here right?
