pfSense

I would like to suggest a couple of improvements to the packet capturing interface.

Snapshot pfSense-2.0-BETA1-20100217-2217

In general, the packet capturing interface works nicely if capturing a few packages in "real time".
However, if capturing megabytes of packages in the background, the GUI does not work well.

(1)
When opening the Diagnostics -> Package Capture tab, it is not immediately possible to see if a capture is already running.

(2)
When a large number of packages have been captured, and "Download Capture" is pressed, the GUI will try to show all the captured packages.
This will render the GUI non-responsive for a long time, if there are a lot of packages.
I would suggest adding a button called "Show last 100 packages" or "Show last packages" and a field to enter the number of packages to be shown.

(3)
It would be great to have an option to limit the number of captured packages per file like "tcpdump -C".
This should be accompanied by an interface allowing to download either one of the package captures.
