UX design improvements

[ZhaoTianPu]

Potential improvement on UX

• fit stage information hierarchy
• hierarchy of labelling and transition - need to let user aware that label is a group/set property rather than a property for each individual point
• which use case is more frequent? user first label for a group then fix the label, or user change the label frequently at a later time?
• reorganize settings - make it under the figure?
• calibration button, extract icon and the extract mode currently share the same button - need to find some better one!
