I'm sorry about the spacing problems; I didn't even notice. I think
it's due to the use of Kwrite.
Chromahold is used to discolour the frame except for one specific
colour (Schindler's list's little girl's red coat!). I removed
Ciescope (and put it in "Test") because we already have Videoscopes
that is much more convenient to use.
And yes, Blue Banana is so powerful that it can also be used as a
Chroma Key! (I'm preparing a video these days).
However, they are only my suggestions, other changes are very welcome.
