With the buttons Add, Delete, Edit and Copy you can add new filters or delete filters which are no longer needed; we will skip this feature for now, because it is not essential for the setup of & knode;.
Cos botóns Engadir, Eliminar, Modificar e Copiar pódense engadir filtros novos ou eliminar filtros que xa non se precisen; saltaremos esta función polo de agora porque non é esencial para a configuración do & knode;.
