A little food for thought........ Editable Filters
There is a good solid reason why,
up to now, filters and adjustment layers don't mix. A filter you apply once and it's over, but the effect of an adjustment layer is recalculated
in real time every time you make the slightest alteration.
An adjustment layer works on each pixel of the image
independent of the next so the calculation is pretty quick.
A filter, on the other hand, can calculate the interaction of a whole area of pixels and so some filters (example Diffuse> Anisotropic) can take a l-o-n-g time to run.
If a filter is going to act like a real-time adjustment layer then to be viable it will need a very fast processor - or you're going to need a lot of patience!
Just like a new release of Windows

, if you want to use the new version - you may have to say goodbye to your old faithful machine
