Option to use limelight only for comments?

Just found this plugin and it struck me that the idea would be very useful in highlighting comments when the cursor hovers them. I typically work with very dark comments and when trying to read them I simply turn on the visual selection.

Would it be possible to make this plugin temporarily brighten the comment block when the cursor is on it? Or would this functionality be better implemented elsewhere?

Start by reading the limelight.vim plugin entry point and its existing visual-selection behavior. Determine how comment blocks and cursor-hover events would be identified, then define completion as temporarily brightening only the comment under the cursor without changing other highlighting.
