How to get "configure" icons next to each block back? My configure icons have disapeared. How do I get them back?
If you are referring to the gear icon that appears when you hover the mouse over a block, that is output from the Contextual links module that comes with Drupal core.



The same module adds contextual links to other parts of a page, such as a node.



It also handle the gear icon that you see in the page to edit a view.
