5. Symbols. Change one thing

— it changes everywhere.

Use symbols, use symbols, use symbols. A symbol is a group of elements you can re-use. Change one thing in a symbol and it changes everywhere. What you do is that you select a group “⌘+G”. After you’ve created your group you click Create Symbol in the toolbar and you have a symbol (shown as two arrows going around in a circle in your layer list).

The Create Symbol icon

Below is an example of a symbol. It just makes working with your design feel so much nicer when you don’t waste time on repetitive tasks.
