It would be helpful if rules could be viewed in expandable groups rather than a single long list.
For example, I have seven rules to allow traffic for one client application. It would be much easier to read my list of rules if I could collapse all of those into one line.

Center aligning all of the columns makes it much harder to read. Please left-align the "Source", "Destination", and "Options" columns.

Enabling and disabling logging without having to go through and edit the rule would be nice, too. Just turn it into a check box like the "Enabled" column. And having graphics for those checkboxes is a pointless waste of resources that makes it harder to read.

I know that much of the layout is going to change in v. 8, so maybe these are already in the works.
