Is it possible to keep the cached visualizations? Generate previews early and make them faster?

Hi, i really like to use this tool with LF and Foot Terminal, it's a great tool and thanks for your work

I don't know if this is possible but after i close the LF the cptv have to generate the previews again, is it possible to keep the generated preview images?

It seems to me that the images are generated when the file is selected, is it possible to automatically generate previews for all files when i select a parent folder or something like that?

The previews generated have a quality waaaay better than what i need to identify the files, is it possible to make it faster?
