I see all the crickets have come to this F/R to hang out. This is a pretty important improvement for using NetFlow for incident research. For example, if you find an IP that is doing a lot of traffic while trying to identify a problem and that IP is harmless, I should be able to filter the harmless IP out of my search as I iterate. There is currently no non-API way to do this. If the filters could be complex with AND/OR/NOT and groups, then it would be much simpler to make use of the data for real world investigations.
Similarly, it seems like saved filters are per-user and it would be far more useful if they could be shared across multiple users.
