Looks like the plugin has been removed from the WordPress plugin repository, i don’t know why but the developer started actively maintaining it some days ago after 2 yr break. Looks like content aware sidebars is your best bet right now and unfortunately i found it also too complicated so i cant help i’m afraid.
