Photoshop CC 2014: All in all the user interface is not consistent.
The Photoshop colour picker from e.g. filter gallery (top) is not used in e.g. Picture frame and Flame (bottom) where instead the crappy standard Windows colour picker is used.
All in all it feels like the usability and design is inconsistent and some (e.g.Picture Frame and Flame) are simply not up to the standard in Photoshop.
The sliders look different, as do buttons dropdown menus, text fields etc.
In Tree the angle is set using a plain slider and not the angle control from e.g. Inner shadow.
Some filter windows have an icon at the top left corner while most don't.
Some filters use a window of their own, some (e.g. Filter Gallery) show multiple filters in one window and others (Blur Gallery) integrate as panels docked at the side.
Is this really representative of your ambitions and best effort in usability?
