This userscript adds several options to the sidebar of Close Review: 

![sidebar][1]

The options invoke API methods to downvote the question, or to vote to close. Voting to close does _not_ count toward the daily limit of review tasks. However, it advances the queue by automatically clicking Skip button. Downvoting does not advance; thus, one can downvote and then vote to close. 

Duplicates, migration and custom close reasons are not included in the options. The descriptions of off-topic reasons are not provided: the script targets experienced users who are expected to remember them. 

GitHub link will be added soon.
