Opening chat or the filter panel between calls now tucks the call list dialer into its collapsed bar instead of closing it, so you can add a note and pick up where you left off. If you place a quick call from a lead’s page during a session, the call list dialer comes back when that call’s dialer closes.
If the page reloads while a session is running, for example after the browser puts an idle tab to sleep, the dialer reopens on the lead you were on. Leads you already called stay marked as done.
