Is there a concise, clear description anywhere of which properties (e.g., size, color, text, etc.) are controlled by a symbol, so that when you change these properties all instances are changed? And which properties are "local" to the instance, so that you can customize a symbols appearance depending on the context you want to use it. I'm interested in all the symbol types (button, graphic, animation).
In the Instance, you can control size, opacity, position, Live filters and blending modes. Altering any of these settings only affects the currently selected Instance, not the symbol.
Can't you also change the text on a button without affecting the symbol?
