Drag and drop variables and styles to apply fill and stroke color

Please make it possible to apply colors to a layer’s fill or stroke by dragging variables from the Variables window or styles from the Design panel onto the layer. This will make it much quicker and easier to find and identify the desired variable or style and then use it to colorize a layer than having to remember a name of a style or variable and then search for it using a tiny popup menu that only shows a max of 10 rows.
