Edit-in-place functionality has been part of Flash for a loooong time, and now it's part of the Fireworks public beta! Double-clicking an instance on the canvas no longer opens a separate document window. Symbols are edited in the same window, and breadcrumb navigation, similar to that in Flash, appears at the top of the window (see Figure 8).
If the symbol has 9-slice scaling applied, double-clicking opens the symbol in isolation mode, which is similar to the old symbol editor document window, but now you're just drilling down into the main canvas (see Figure 9).
Symbols without 9-slice scaling offer in-place, live update of your changes. Double-clicking this type of symbol fades everything on the canvas except the active symbol. As you make changes, those edits are reflected in all other symbol instances on the canvas immediately, without having to click back to the main canvas. This capability can be very useful for experimenting with button designs, or the ever-popular "pod" containers found in many contemporary web designs (see Figure 10).
The Button Editor has changed also—it's gone! Well, perhaps relocated is a better term. When a button symbol is double-clicked, all the functionality from the old Button Editor is displayed in the Property inspector (see Figure 11). This change is great because it prevents another document window from cluttering up the workspace.
Support for 9-slice scaling with nested symbols is now a reality, so you can have multiple nested symbols that scale intelligently, based on the main symbol's scaling guides or each nested symbol's own specific scaling guides (see Figure 12).
