How to remove the annoying new column in admin area?

I fixed the issue by removing all code between class Bulk_Edit { } from the file admin > modules > class-bulk-edit.php

Please consider adding option in your plugin to disable the bulk editor.

You can hide the columns (and any others) easily by pulling down the screen options from the top right and deselecting them.

I’ll also add the option to totally disable the Bulk editing and quick editing feature.
