Digital BW, The Print

Hello

I just downloaded the latest (demo)version of my favorite conversion
tool, which is still the one available back in June 2003 (I think it
was simply called "Convert to B&W Pro" at the time).

The Imaging Factory people have changed the user interface quite a
bit: I miss among other things the PS and the FP4 curves. As I only
use this PlugIn for single file conversion and as it seems to work in
16bit mode as well even though on their homepage it says for the new
version

"optimized engine that favors 16-bit processing"

I wonder whether its worth upgrading.

Am I missing something? Any comments? 

Thanks
