Adds the internal item id as a tooltip on each message-list row, handy for debugging.
Code to copy
// Append the internal item id as a tooltip on each message-list row
function tagIds() {
document.querySelectorAll('div[role="option"]').forEach(function (row) {
if (row.dataset.jzTagged) { return; }
const id = row.getAttribute('data-convid')
|| row.getAttribute('data-animed-list-item-id')
|| row.id;
if (id) {
row.title = 'item: ' + id;
row.dataset.jzTagged = '1';
}
});
}
tagIds();
const obs = new MutationObserver(tagIds);
obs.observe(document.body, { childList: true, subtree: true });How to use this example
