I hope it is easy to use and doesn't consume much resources. in k9s I love how quick it is switch through panes using commands followed by : or quick to search through /, even though it is GUI, I would recommend trying to make it as much easier to use via keyboard shortcuts as possible, if possible try to use the same commands k9s has, or take vim for example, this would help fuse both audiences, the k9s lovers and the k8lens users.
