1. In General -> Configuration the trashcan panel should look good and the button should be of a text kind with an icon. Make the other fields disabled when trash is not enabled.
2. Trashcan in tree browser - Should have a better color than red, replace the icon. Context menu : Empty Trash should be red and have a relevant icon.
3. When deleting an artifact permanently (when the trashcan is disabled or from the trashcan) - the word permanently shouldn't be upper cased and should have an alerting color.
