Query on a Plugin (Combine/Minify)

Hi,

As far as I’m aware, this doesn’t yet exist – or maybe it does?

I was looking for something along the lines of W3 Total Cache’s file help wizard, whereby you can add certain files to a list of default (blocking), async, or deferred, scripts and CSS.

I’m having problems with W3TC itself, in that it’s crashing my website, but the above feature is excellent.

At present, there only seems to be plugins that give you an option to add a list of scripts and CSS that you DON’T want to add – dunno, might just be me, but I’d find it much easier if I were able to add things one by one and see the results, rather than remove them one by one to eventually find out which script is buggering my website up.

Any advice on the above would be much appreciated!
