Problem / Steps to reproduce

I love, love, love the new preview-window options (base scroll/offset/denom). I've been adding them to my workflow. I find myself sometimes not using them when I'd like to because I have an alternate preview() action bound, but the preview window settings are different for them.

As an example, imagine using fzf to explore a merge conflict. Your preview window jumps to the offset in the file with the merge conflict: --preview-window=+{2}/2. You've bound keys to change the preview to show other indices, however - something like --bind=ctrl-l:preview(git show :1:({1}),ctrl-r:preview(git show :2:{1}). But the field index expression in your preview-window hasn't changed. Even if your search result has the desired lines for each index, you can't change the preview-window option to use different field index expressions.

Let me know if this hasn't been clear, and I can put together a more concrete example.

If this doesn't match your vision for the tool, that's great too - I trust your vision for the tool much more than my own. Thanks for making something that brings so much joy to my development experience, dozens of times a day!

Thanks for the suggestion. I agree that this is needed. We could also use it to change the position or size of the preview window.

Thanks!!!
