Features for new releases

Hi,

I'm using NetFlow Analyzer for about one week and I can say I really like it. It has almost everything I need for analyzing netflows and it's quite fast.

First few questions:
How long the data stays in database/and in which resolution (10min, 1h,, 1 day...)?
After some time that data is deleted or what?
Is it possible to make backups?

Now I have some suggestions for future releases .

1. something to change the size of graphs - to make it bigger
2. something to fix max value on y-axis (per interface max bandwith, or something..)
3. mapping on graphs - that I can select with mouse some period on the graph and than zoom it (from time to time)
4. more properties on "Custom Report" - that I can include some graphs, make summaries, etc.
5. !!!! summary per subnet basis - that I can see total amount of traffic per one subnet (it would be also nice to have total per application per subnet)
