I can not thank you enough, I've been searching for the last couple of years for something to do exactly this.
In my site I have a publications grid (ordered by date) and I'm constantly changing them to alter the order.
It is very time-consuming, and I still can not believe WP does not have a built-in feature to do it in bulk.
So this plug in is a real saver! Thanks a lot, and hopefully this plugin will receive many more reviews and downloads!
I can't filter on "products" to change their dates, only after lots of clicks and scrolling to all media, pages and posts... It's not a very user-friendly plugin. Normally one should be able to select products > edit > change date ...
