After several hours trying to tweak this plugin on existing website i give up.
First this plugin have too manu options that are for average user on existing site very complicated.Minify work partialy,some plugins are unusable after activating that options,for example im usibg buddypress with WP plugins that doesnt work with that are
compehensive google map
slide deck 1
super slider login
after that i give up to try whatever else dont work on default settings.I tryed also to enter manually path to scripts to avoid those plugins but then comes CSS minify.CSS styles for some browsers work and for some not example (something stay same on mozzila but on Chrome missing many icons,CSS animation effects etc..)
i didnt test rest becouse i loose my nervs :)
plugin is speed up my website and good is for browser leverage caching but my honest oppinion need more bugs to be filled.Great job for increasing page speed but there is no use when half plugins that are popular doesnt work on it.I hope that will be solved in some next release :)
