hi Svet,
1. You're right. The personality files support scroll for each wheel, although only in one direction. The Cuelux UI only features a scroll control for the first (color/gobo) wheel. It's just a matter of the lack of screen space to add more controls. If the demand is there then I don't mind extending the personality file system to support both cw and ccw scrolling, so far I just haven't the added advantage for choosing a direction on a scroll.
2. Yes, this is a bug. The Shake control should become available. I'll sort it out.
3. Correct, only the customs can be renamed. Please keep those names short as there is little space in the UI
4. Well spotted. The engine is strong in realizing some functions share the same DMX channel and are therefor mutually exclusive. But it would be better if the both scenarios you've outlines behave consistent. I will address it.
5. This is the 'Barrel' control. E.g. Martin Acrobat uses it.
Thank you for your feedback!
