I’m sure that some of you have noticed that the interface for the Fill dialog box has been updated in the latest version of Photoshop CC. Now, you only see the options that you need for the types of fills that you want to apply. For example, if you simply want to fill with a Color or History, then the Opacity, Blend Mode, and Transparency options are available. Note: the transparency options are available if you have selected a layer that has transparency.
If you choose to fill using Content-Aware, the Color Adaptation option becomes available.
If you choose to fill using a Pattern, then you have access to Custom Patterns as well as Scripts such as Brick Fill and Place Along Path. Note: the Photo Frame and Tree scripted patterns can now be found under Filter > Render…
In addition, you ‘ll see that the default patterns have been updated for patterns (both in the Fill dialog as well as in Layer Styles).
