To help manage large numbers of saved filters (personal or shared), we need to add categories to filter subscriptions.
e.g. Using tabs under the saved filter portlet & manage filters screen, the categories could be personal/my, favourite and all.
- Personal - would be all the filters the user has created - with a checkbox next to all to mark them as favourites.
- All - would be a list / search function (depending on number of filters available) that would also include a check box next to each to mark it as a favourite.
- Favourites - would be any filter marked as a favourite.
