- Save recipient edits and sender choices with reply drafts. - Keep CC and BCC open when an address is cleared. - Allow SMTP without credentials when authentication is off. - Use the workspace timezone for reports and campaign dates. - Show CSAT responses without reloading the conversation. - Block access to attachments from deleted messages. - Accept conditional email templates and catch missing or repeated replies. - Explain why choosing another default email template failed. - Reload stale routes and keep widget image fallbacks working. - Keep the launcher usable by keyboard and reset host button styles.
