Hi, Playing around with the pluggable widgets. Works nice. Are you using Sass within your widget (at dev time) and compile it to one [WidgetName].css? Did you create your one task for it? Maybe this could be done in the Pluggable-widget-tools ? Sven.
I haven't seen pluggable widgets with SASS instead of CSS yet. Since too much CSS within a widget should be avoided there doesn't seem a strong need for supporting SASS yet. See the Mendix repo of pluggable widgets:
