I often get frustrated when typing long policies in policy-playground because I can't use the arrow keys for navigation. When I wanna slightly modify just entered policy, I'm forced either retype the entire policy or copy it somewhere, modify it, and paste it back.

Describe the solution you'd like

I suggest using the chzyer/readline library, which is already used in frostfs-adm. This would enhance prompt navigation, allow to use shortcuts and command history.
