Yes, it is a big red flag telling me that the combine is unimplemented. It is currently on many things since I recently redid the combiner (sometime last week I believe). In the release version the red won't be there because first of all, I will implement many more combiners, and secondly, I will probably tell it to just use the previous combine instead of making it red. (I already have a #define BRIGHT_RED that can be commented to do this)
btw, I think I will make this version 0.1, it's much much farther than 0.04, so I think 0.5 would really be off-scale.
Don't ask for release dates yet, I still have a few more things I want to do to it. (right now I'm expanding the configuration dialog) Also, we are going to have a testing period that will allow Ogy to update his compatibility list and me to write the necessary documentation/site updates/whatever.
btw, don't ask to be a tester either. it's a testing period between the people working on it, not the public.
