MW 1.35, SimpleBatchUpload 1.6

Symptoms: No drop area on upload page (just a file upload button), error on Chrome console stating jquery.ui.widget is deprecated

Fix: in src/SimpleBatchUpload.php, replace

'dependencies' => [ 'jquery.ui.widget' ],

with

'dependencies' => [ 'jquery.ui' ],

Thanks for reporting. Added to the GitHub issue tracker
