I don't usually review applications, but WP Reset is one of those "must haves" & "I didn't know I needed it" until you realise that after all the hours spent, something has gone wrong - and you didn't back anything up!
The free version is amazing, but the extras in the pro version far exceed what I thought I was buying, for example the snapshots. I am just learning developing on WordPress & sometimes, I want to go back & redo something. Of course, if developing locally, you just make another website, but with WP Reset, you have so much control over what you can do, but what happens if on line & then the worst nightmare: WP Reset’s Emergency Recovery Script to reclaim your website!
I am still going through what is available so when I saw this on AppSumo - which I knew nothing about - I thank whichever website linked to AppSumo to purchase. It's a great offer, so thank you WP Reset & AppSumo!
