Michael Fabian 'Xaymar' Dirks f01d2e6db1 filters/sdf-effects: Improve user experience with visual property groups 
Grouping properties by what they do improves the user experience as the user does not have to guess at what belongs to which part of the effect. Additionally toggleable groups automatically disable all child elements, so the user is not confused by them still being active.
