(I did a feature request in the bugtracker here
https://bugs.kde.org/show_bug.cgi?id=3D256175
The description was not very clear but this is exactly what it was about)

      That&#39;s the idea, but exactly &quot;the combined transparency (alp=
ha
      channels) of the layers under the new layer&quot; is not &quot;copied=
&quot;=A0 to
      the new layer, you still paint on the whole page, as with any
      other layer blend mode (meaning if you turn it back to Normal
      blend mode the &quot;blend effect&quot; disapear=85)<br>
      <br>
      I use this painting/layer blend mode on TVPaint (the best
      commercial Painting application to me ;) )<br>
      (There was an open beta for Linux but it was usable until January
      1st, I don&#39;t think there is a new one yet. If you can try the win
      or mac demo)<br>
      <br>
      Also this blend mode is in Open Source app SYNFIG STUDIO !!! it&#39;s
      a vector program but the Onto mode is there (with a few original
      useful others, like Straight and Straight Onto=85)<br>

    Ah... ok... now i understand. This mode is meant for layer
    compositing.<br>
    I see how it works. It would be no problem to add this blend mode.<br>
    When/if i get a developer account and everything is all right with
    the &quot;blending modes&quot; patch so<br>
    it can be applied, I can add this mode... would only take a few
    minutes :)<br>
