Would be nice to have a tool that would show growth of database, instance, Server over time with forecasting to provide approximate time until disks are full. I know there is alerting for disk capacity in SQLdm, but Capacity Management and planning would help in sizing for new servers and disk arrays. Especially helpful when it comes to sharepoint dbs. At an old job, they had the Quest software suite and there was a stand alone tool called Capacity Manager that I used all the time. Wrapped inside was a Job Manager and scheduler as well. I found it very useful.
