See also offset in packet byte pane.
Can we add an edit box or something to change the start offset to show a slice of packet with new relative offsets to the left side in the packet bytes panel (3.20. The “Packet Bytes” Pane)? So I can quickly find the relative offset of a field or a byte from the bottom left corner of the status bar.
It looks like the 7.3. Show Packet Bytes triggered by clicking the "Show Packet Bytes (Ctrl+Shift+O)" menu item and selecting "Show As" "Hex dump" in the Packet Details Pane.
