Show a "-" instead of "0", when "@Enter" is pressed

While the value is manual (red) it will display 0.  As soon as you Update the Cue, it will convert to a "-".

Yes, I noticed this, but it would make sense if it would be displayed as a red "-". In that case, you could difference it from an actual "0"

It seems to me you are looking for [at] [Enter] to behave like [Sneak][Enter] in this case. At Enter enters hard 0s in manual control because you've grabbed the channel and manually entered values. A red "-" would indicate to me that I manually have controlled the thing which I don't manually have control over (because it's a tracked in value, not a manual value)

A magenta 0 will display as -, all other 0 will display as 0. You're seeing a red 0. Manual values have no knowledge of previous cues because before you record those values it's unclear where within the cuelist they will live. Without a previous cue the console can't decode if the 0 will be blue, green or magenta. Or you could evenrecord the 0 in a sub and it would turn yellow.

So no, I don't think a red 0 should show as red "-" because aamagenta "-" it's only one of four possible cases.

Didn't think about that case, but you are absolutely right!
