I am specifically intrigued by 3 & 5.
I am really hoping 3 allows for the ability to ignore all interfaces upon discoveries for servers. We monitor the ports on the switches not both ends so this would be particularly handy to us.
Improvements to the DB performance and more efficient queries from the front end are always welcome. We have documented several long running queries that hinder performance that are generated by either the Map resources or the last events resources. I have actually written a custom last 50 events resource that is much more efficient and replaced it on my views. As for the maps I have taken them off of the views that everyone loads and instead replaced them with a link so they can be loaded as needed.
