Remove unneeded whitespace

[mike-lloyd03]

Is there a way to configure which-key such that extra "whitespace" around the command list isn't rendered?

For example, I have this

I'd like a single column, right aligned to not take up prime real estate on the left side of the buffer. Something like this is more desirable:

I achieved this by setting the left margin really big but it doesn't translate to different window sizes very well.

Is there a way to cut out all that extra unnecessary whitespace?
