You can save filters that your Users can use day to day. These will show up in the left hand navigation bar.
Open up the Table you wish to create a Filter for by selecting it from the left hand navigation bar.
Click the Filter icon in the top left. You can then use all of the Filter functionality as documented in the Using a Gridfox Project help but have the additional option to then save the filter for your Users.
To save a new filter, click the Save As button. Give the filter a name and click Save.
This new filter will now show up in the navigation bar for your users. It can also be used as the filter for scheduled workflows and charts.
