Hi Gilles,
here are my comments on the b&w conversion tool:

I find it much clearer now, as one can see all available options at once 
without scrolling through the combobox. Also the contrast tool comes in 
really handy when working with b&w. 

For convenience of operation, I would like to be able to scroll through the 
options with the keyboard arrows as it was a case with the combobox.

I'm not sure that the split window between color and b&w is of much use, 
because one usually does not compare these two modes, but it could be useful 
for another comparison:

I think there are actually two groups of options, the filter/mixer options 
(neutral...yellow) and the tonal options (sepia...platinum). The second group 
should be able to be applied on top of the first group. So, my idea would be 
to separate the two groups, make it possible to combine the two groups, (e.g. 
Yellow Filter with Platinum tone) and maybe to use the comparison split to 
show the effect of the second group.

Thank you very much for your great work Gilles.

Gerhard
