We would like the out-of-the-box Sketch component in the ArcGIS JS API to have to ability to draw and edit polylines, polygons, etc... in different colors & opacity rather than creating that ability on our end using custom code. For example, when a user clicks on a single polygon to edit in Sketch Tool, provide additional buttons, color picker, etc... in the tool UI.
