Google page insider and other html analyse tools recommend  remove dependencies from css and js, because they delay rendering of the visible page area.

There are a few things that i could optimize my dnn pages:
- defer javascript loading. jquery and related library are big which is not good for slow mobile networks on emerging country. If loaded asynchronously would permit render of the page much faster. A loading cursor could indicate that site is still loading.

- reduce resources size. DNN version 8 enable removing default css by using DnnCssExclude, witch is great,it  enable to reduce 100k, but can only remove that resource. Can't find any documentation about it. For most of my site pages i would like to remove all dnn controls and load only jquery and skin.css so speed could be the fastest possible.

So, how can i remove all standard dnn resources from page or better, remove specific ones ?
If necessary to the platform i can write a module that would insert asynchronous load for those.
