vscode git heatmap extension

The git gutter, additions and deletions with different colors is very useful when reviewing current code for changes, but once you commit the code that is gone. A heatmap would be showing the colors somewhere, maybe the gutter, minimap, editor, showing recent changes/activity, around the areas where recent changes have happened. This way the developer can know where some of the recently touched parts of the code are, even if the git gutter is not available anymore. The heatmap could have color intensity denoting more recent changes and less recent changes.
