One of the things I like about Photoshop is the ability to directly merge a layer down to the layer below it, bringing it's blending type and opacity info along with it. It seems as if in Painter I must group and then collapse them... is this correct? Or is there another way to work this? I don't mean dropping a layer, which seems to simply take the layer and merge it with the background regardless of the layer's current position in the hierarchy, but rather the Painter version of Ctrl-E where you are still working within layers above the background after the merge or drop or... what have you.
Also, any hints on working with layer groups so that, until you're used to it, you more easily track what is where? I think layers may be dangerous and too much of a crutch in Painter, more-so then PS, but until I get more comfortabe, they are something of a safety valve.
