Administration theme for the Thunder Distribution that extends and modifies Sevens styles for authoring UX and an integrated look and feel of the contributed modules used in the distribution.

This theme started as an admin theme shipped with the first RCs of the thunder distribution and was based on Seven as a base theme merely containing fixes and improvements of the visual presentation regarding the modules in the distribution.

End of 2016 the Thunder core team started a sub project regarding research and a concept for improving the authoring UX and a roadmap was created that did naturally emcompass a lot of theming modifications that go far beyond mere "tweaks" of Seven. As of now Thunder Admin is based upon Classy as a base theme and a fair amount of CSS and theme hooks are copied over from Seven to reduce the number of overrides in the theme inheritance.

Currently the above history leads to the fact that there are a lot of assets that will/might need refactoring in future development.

• Asset folder structure needs to be improved to follow a clear concept
• image and icon assets need to be consolidated and reworked according to a unified visual language and color scheme
• CSS that was initially only copied into SCSS needs refactoring for clarity and consistent use of variables
• Visual styles copied over from Seven need to be refactored to be aligned with Thunder Admin's design in more areas than the current focus which is content authoring
