Dear Support Team, After the last update, I noticed that the function “Show in topic tree/Im Themenbaum anzeigen" no longer appears in Thunderbird. This feature was essential for me as it allowed me to organize my emails efficiently. Without it, Thunderbird is much less practical for me. Can you please let me know if it is possible to restore this function? If there is a setting or menu field that I can activate, I would be very grateful for brief instructions. Versionnumber: 128.6.0esr (64-Bit) Mac Thank you very much for your support!!
