Please describe the problem you're trying to solve

Having the preview pane is nice on a wide terminal, but on a narrow terminal it takes up valuable space. I can manually toggle it on or off, but when you keep resizing the terminal, it gets annoying.

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

When the terminal is resized, load a ratio configuration based on the terminal size. Like, if the terminal width is less that X cells (~75 in my case) then the ratio should [4 6 0] otherwise it should be the default
