I like to place 2 enhancements for the gallery widget.
-Add multiple filter of same typ. As an example. I have several enumerations and like to have a dropdown filter for each of them. Currently it is only possible to combine several enumeration into a single dropdown filter.
- I like to store the configurations to a attribute as it is also possible in datagrid 2.0. Usally you want to store this information somewhere on a user related object. Define a Datasource and xpath to the users object and attribute to store the information would be helpful.
