Hi, as part of the conversation about width and NaN, other problem was unveiled in Jewel UI Set. It was about the problem from some components to have StyledUIBase that provides different support for jewel styling and other components (mostly containers) composed that functionality but still inherit from UIBase instead StyledUIBase. That always was lacking coherence in Jewel. I solved this today following the pattern Alex make in MXRoyale by recomposing internal classes to extend from StyledUIBase. This should make things in Jewel more coherent for people working in components and other things that use to be more internal or hidden.
