It will be an awesome feature if you put a "Selection method according to attribute"
which means when we need to Select Same color (Fill or Stroke), same opacity, or same appearance. It is so much helpful after tracing an image to select a range of colors. When working on a flyer or packaging design for production selecting similar color or select strokes that have same thickness or fill color to change together all those needs select with attribute option.
Consider a special tool for those selection purpose with a bunch of option to rectify and narrowing selection range or Add all those features to the Move/ Selection tool.
