yes, the evil plan which spun off my posting is to get rid of the layer mode 

In my regard, blending is a complex adjustment rather than the choice of one 
discrete mode.
What is currently called layer modes can be seen as factory presets of a future 
blend tool.
A dedicated tool which allows on-canvas adjustment of blending characteristics 
will presumably
work best.

Using an analogy, the current situation for blending is like not having the 
curves tool,
but only preset curves to choose from. And indeed there's a relation between 
curves and
blending, for each RGB blend mode can be described as a set of 256 curves, at 
least within

But that's a loong way to go, especially if the adjustments shall be 
relevant ones. So the question is what to do right now?
The current set of layer modes seems rather arbitrary to me.

each new mode adds one finer step for adjustment of blending characteristics.

If i want to darken a layer by itself, the curves tool allows nearly infinite
different characteristics of darkening. If i want to darken a layer by another 
there are a total of 3(!) characteristics available: 'darken only', 'multiply' 
and 'burn'.

Of course, there won't ever be enough layer modes, which is one reason why
they have to die long-term...

i'd like to take the same line:
if a layer is just a transparent sheet, and a composition is just a
projection of a stack of sheets, then it's most natural to insert
(photographic) filters in between. Say, a colorizing red glas
or a freaky effect lens, in general: an adjustment layer.
