@hellojukay Great job! Is it possible to add a flag to control the number of items displayed?

just like:

kubecm switch --items-size 6

[hellojukay]

It looks like --ui-size is already supported, we just need to set a larger default value for the option, i have tested it , it works.

$ ./kubecm switch -h
