Overall adjustment layer.

Could we implement an adjustment layer that functions similarly to After Effects' adjustment layer? Instead of duplicating or converting it into a smart object, we could have an adjustment layer positioned above all other layers, capable of applying effects like filters and adjustments.

Not sure I follow. That's how they work now - ? An adjustment layer can either affect all layers, or just the underlying layer, or just the group or smart object. What else do you want?

"capable of applying effects like filters and adjustments."

Could you please provide a screenshot to clarify what you are looking for?

[Andrew Bold]

I take it you mean filters like Gaussian Blur and such?

To apply them on all the layers below without having to merge everything into one layer?

[Tomy25058856hcw3]

Yes!! I'm sorry if my question is confusing

[Bojan Živković]

The only way to apply filters from Filter menu to all layers in the Layers panel is to merge non-destructively (Ctrl + Alt + Shift + E), for example, or to convert all layers to Smart Object layer what will give you opportunity to edit each layer at any time by editing Smart Object layer.
