As the title says. When I filter for adjustment layers, Solid Color (Color Fill) layers don't show. Same goes for 'Gradient' and 'Pattern', so it might be intentional, but it's not how PS CS6 used to work & it kinda breaks my workflow.
I believe that Solid Color, Gradient, and Pattern are considered Fill Layers rather than Adjustment Layers, based on the setup of the Layers menu. I'm still cool submitting a bug report for this, but would that information change your perception of this situation (probably not, but it doesn't hurt to ask...)?
