Solution you'd like

I'd love to see configurable colors in the minimap for the different types of changes (modify, add, delete) git reports.

Additional context

Some IDEs show colors in the side bar to show where changes have been made since the last commit. This makes it easy to click on/jump to/stop scrolling when navigating to recent changes in a file. minimap.vim does not have this functionality, and it would be more awesome if it did.

I can easily see this being out of scope for the project, but I figured not asking gets you nothing. I don't mind taking a stab at implementing this, but I don't have any context for how possible this would be (I haven't browsed the source to see how minimap.vim works).
