// To do:
// - https://gitlab.com/wireshark/wireshark/-/issues/6727
// - Wide last column?
// + No arrows on unsorted columns
// - Add follow stream to context menu
// + Change "A <- B" to "B -> A"
// - Improper wildcard handling https://gitlab.com/wireshark/wireshark/-/issues/8010
// - TShark consolidation https://gitlab.com/wireshark/wireshark/-/issues/6310
// - Display filter entry?
// - Add follow, copy & graph actions to context menu.
// Bugs:
// - Slow for large numbers of items.
// - Name resolution doesn't do anything if its preference is disabled.
// - Columns don't resize correctly.
// - Closing the capture file clears conversation data.
// Fixed bugs:
// - Friendly unit displays https://gitlab.com/wireshark/wireshark/-/issues/9231
// - Misleading bps calculation https://gitlab.com/wireshark/wireshark/-/issues/8703
// - Show Absolute time in conversation tables https://gitlab.com/wireshark/wireshark/-/issues/11618
// - The value of 'Rel start' and 'Duration' in "Conversations" no need too precise https://gitlab.com/wireshark/wireshark/-/issues/12803
