The next release will have a "max-idle" that can increase the amount of time flows will stay when idle. However, ovs-vswitchd can still remove the flow before that time. It's really a testing knob, though, and not meant for end-user configuration. It will likely be removed in the future.

Not without a major rewrite. We often get this request, but haven't seen a compelling reason in practice. If the default behavior isn't working properly, we should look at whether we can make it better.
