This is the next version with another enhancement planned - sorting resource list by custom field values. The fields with numeric representation (numbers, date, rating) will now be available in sort options for a category where they are available. The fields can be chosen to be added to the list from Edit Field page.
In this version, we have implemented Auto Reload option via AJAX.
Any change in the filter form will update the list of resources via AJAX and show the filtered list along with active filters. Clicking on active filters on top of the list will remove the filter and update the list without a full page reload as well.
At the same time, current URL keeps updating with the latest filter data, so users can just copy the URL and send it via IM and the URL will represent their currently filtered list (supported in modern browsers only).
Please note, that activating "Auto Reload" feature server load will increase considerably if you have too many resources. Every update of the list causes two AJAX queries, one of them running the search engine to get the filtered resource list.
