Is it possible to make the fuzzback accept external configuration

[liangkarl]

Hello,

Is it possible to let fuzzback accept external configuration?
In my case, I placed the fuzzback window in the bottom, so fuzzback pane had the same width as my console.
The benefit here is that I don't need additional preview view and the longer lines in the fuzzback list will never be hidded.
However, I have to add an additional parameters for fzf, fzf --pointer= --marker= --no-scrollbar ..., but there is no proper place for me to added it.

Could you add an entry for this? Thanks.
