Auto-display latest live-feed packet in detail pane?

Unfortunately, while Wireshark has an option to always show, in the packet list pane, the most recently captured packets, it does not have an option to always select the most recently captured packet. That would be a problem if it were the only behavior available - if you wanted to look at a particular packet while a capture is in progress, it would keep un-selecting that packet and selecting the most recently captured packet - but it could be a useful option. You should file an enhancement request on the Wireshark bugzilla.
