Ah no... If I take this approach, then I can no longer compose a scene 
from different queues.

Suppose I have 5 channels and this queues:

202.1 = 100% 100% 0%   0%   0%
203.1 = 0%   0%   100% 100% 0%

So this:

show 202.1 for 0.05s, crossfading for 3s
show 203.1 for ever, crossfading for 3s

Would result in channels 3 and 4 at 100%. Whereas the same would result in 
channels 1,2,3 and 4 to 100% if I replace the 0% values with inactive 
channels... I thought that was the whole point of "composing scenes" out 
of different queues... which is what I want.

The whole reason for this approach is that if I change the value of one 
channel in one specific "part of a scene", it is automatically changed in 
every scene that uses that "part", because that part is one (and only one) 
queue, for which the values are once (and only once) defined.

It doesn't happen that much (in our show) that a whole complete queue is 
used more then once, but it happens all the time that parts of queues are 
reused. You could imagine the scene being composed out of different blocks 
(call them A, B, C, D, ...) and sometimes we need lights on A, another 
time on A and B, then on C and D, then on A and C, and so on... Every 
block (A, B, C, ...) gets its light from typicaly 3 to 4 channels (being 3 
to 8 spots). If I change the lightning on block A, I want that change to 
be visible in all scenes that A was part of.
