Grouping UI controls
Sometimes you might want to group some controls to better align them or move them all at once. To group a set of controls, select them and hit CTRL/⌘+G on your keyboard or use the Group command in the Edit menu (Top Bar). The controls will change color to purple to indicate that they are grouped. Once grouped, the controls will behave as one when moving or aligning. To ungroup controls, press CTRL/⌘+SHIFT+G on your keyboard or use the Ungroup command in the Edit menu.
You can double-click on a group to "enter it" and edit its contents. A small floating breadcrumb bar will indicate that you are editing a group and allow you to navigate back out of the group (you can also use ESC).
Groups can also be nested (i.e. a Group can contain another Group).
