Telegram: collapse quoted replies

Shortens quoted reply previews to a single line and expands the full quote on click.

Code to copy

// Shorten quoted reply previews so long quotes do not crowd messages
function trimQuotes() {
  const quotes = document.querySelectorAll('.bubbles .bubble .reply, .Message .EmbeddedMessage');
  quotes.forEach(function (q) {
    if (q.dataset.jzTrim) { return; }
    q.dataset.jzTrim = '1';
    q.style.maxHeight = '38px';
    q.style.overflow = 'hidden';
    q.style.cursor = 'pointer';
    q.title = 'Click to expand the quote';
    q.addEventListener('click', function () {
      q.style.maxHeight = q.style.maxHeight === 'none' ? '38px' : 'none';
    });
  });
}
trimQuotes();
const obs = new MutationObserver(trimQuotes);
obs.observe(document.documentElement, { childList: true, subtree: true });
