Multiple Bump Maps and Filter Snippet Library

So, they're two separate wishes....

For 3D people, I'd love some sort of an ability to put larger distortions into a displacement map layer, and finer, noise like distortions into a bump map.

Especially for use in the applications that haven't gotten into using normal maps.

Sometimes I take the Bump map and plug it into a renderer displacement map, and plug the normal map into bump channel. Sometimes it works out, sometimes not

The other one would be a sort of an asset browser where people whom make filters can save filter snippets, and then be able to quickly retrieve them when making a new filter.
