RustRover - change how errors and warnings are highlighted?

Currently I find it a little difficult to locate the any lines with errors, warnings, or typos.

Is it possible to highlight the text background (like how when you select text), or put an icon in the gutter to better indicate the line?

I know that there's an icon in the scroll bar, but that doesn't line up with the line so it's not that great of an indicator in my opinion.
