The filter section that can be used in different places is useful, but it could be much more useful if the user could save more than one filter. 

For example, when the user clicks "save flter" the page could ask for a filter name, and a "saved filters list" could appear somewhere in that section allowing to apply in a single click different conditions.

I understand that there could be a problem with the filter values, that can change over time, but still I think that this function could be quite useful

Thanks a lot
