I am aware of Perfmatters but I want to use WP Shifty.
Why?
In a very simplistic form, they both are plugin management plugins but the main difference with WP Shifty is that you can check a live preview of the impact of the changes you´re making in the frontend
BEFORE YOU IMPLEMENT SUCH CHANGE.
How is this possible?
Take a look at this video tutorial to see what I mean...
So, the main benefit is that you can check if any changes you make while working inside the plugin will break the site so you can make the adjustments BEFORE saving/implementing such change.
As a matter of fact, I love Perfmatters so much that I actually contacted them and ask them to consider implementing this feature inside their plugin and I got a reply from Brian saying he found the feature very interesting and he instantly added it to the plugin feature request pipeline...
But, while I wait for the Perfmatters team to roll this feature, I am "stuck" with WP Shifty.
That is, if I can convince a benevolent soul in here to null it
