I considered the same option but then I recalled that this is reported as a security matter by my hosting and suggests me to disable the scripts concatenation.
I am sure there is at least a non standard way I can achieve this with your plugin but I will not give high priority for now as I need to finish the project first.
Thank you very much.
P.S Great plugin!
It has an impact though in time spent in the admin area by the managers.
I did read in the code after trying to hack into the plugin that you only buffer the frontend requests.
So, as I believe it safer not to hack deeper, I wonder if there is a hook or an API call somewhere that I can use to join-minify the static files in the admin area that I consider safe to be joined.
Thanks for your answer in any case!
