SNMP Discovery

I feel a great addition to the Zabbix machine would be the ability to give Zabbix the ability to discover available SNMP MIB/OID's for a device. It seems plausible that an SNMP walk could be performed and the results could be chosen from to add an item(s). This would save the time of performing the walk manually and prevent typo's..and present a user with many more choices for monitoring options.
