High-level wish list:
Allow filtering of specific files or folders within library paths so that in the collection window I can do something similar to:
- right click on a specific collection to access it's underneath properties
- add-up filters for files types and mostly directories (such as @eaDir pseudo-hidden directories from a commercial appliance).


Detailed request:
I've always been using digikam for my photo library.  Since a little while I bought a synology NAS and it automatically creates @eaDir with thumbnails.  This gets automatically generated there is no good way to get rid of them.  Therefore since then I cannot use efficiently Digikam because of this.  All I'd need is a filter that can be applied on that specific collection and I would be good to go!
