Whouldn't that be the same as Gimp/Photoshop?

By an explicit mask I mean a mask that isn't built-in. In Krita the only way
to do that would be to have a child.
Such a mask could be turned off or moved without, while for example the
adjustment layer stays in place (then working on the whole image)

Let's say you would minimize Layer 1. As a result the layer box would only
show Layer 1 and the masks would be hidden. The small thumbnail would show
the content of the layer, but not the effect of the masks applied to it. It
would be the same no matter if the tree is collapsed to the top or the
bottom.

On the other hand the group layer would show a thumbnail of the layer with
all filters applied.
