I installed it with the only hope it would recognize Redis URIs like redis://name:password@host:port/db, unlike redis-cli, which requires me to type each part of the URI separated in different flags I never remember.
Turns out it doesn't, but maybe someone will hear me in the future!
I just took a peek in the code to make sure it didn't use the "keys" command. I see you give a warning for a list of dangerous commands. Good thinking!
It even highlights keys and values differently: https://i.imgur.com/mrOMBUi.png
It also handles redis server weirdness as well by faithfully relaying error messages.
I haven't explored the tool too deeply but would it be possible to get keys from redis itself to assist with auto-complete?
