Describe the feature or problem you’d like to solve

A file in a gist gets overwritten if a new one is added with the same name.

Proposed solution

Gists renaming would let you have multiple variations of a configuration file on different hosts in the same gist.

gh gist rename would let you move a previously uploaded .zshrc to .zshrc-host1 , add the current one to the
same gist and then rename it to .zshrc-host2. Or with it you could give a meaningful name to the files just called
config like in the case of the MPV configuration, that is ok when they in the right directory but not out of context.
