text: Title: Add a "Hide all Chats" button
  Body: I created this lame code to delete all of my conversations using Javascript, which I then put on my browser's developer console to run.
  
  ```
  // Version 2.0
  var xpath = "/html/body/div[1]/div/div/div[2]/div[1]/div/div[2]/div[1]/div[2]/div/div/div";
  var elements = document.evaluate(xpath + '//a', document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);
  var aTag_count = elements.snapshotLength;
  console.log(aTag_count);
  
  for (let i = 0; i < aTag_count; i++) {
      var DeleteConversation_button = document.evaluate(xpath + '//a[' + (i + 1) + ']/span/div/div/div/button[2]', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
  
      if (DeleteConversation_button) {
          DeleteConversation_button.click();
      } else {
          console.log("Delete Conversation button not found.");
      }
  }
  
  setTimeout(function() {
      for (let i = 0; i < aTag_count; i++) {
          var Dialog_button = document.evaluate(xpath + '//a[' + (i + 1) + ']/span/div/div[2]/div/div[2]/div/section/footer/button[2]', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
          if (Dialog_button) {
              Dialog_button.click();
          } else {
              console.log("Dialog button not found.");
          }
      }
  }, 200); // 200 milisecond delay
  ```
  
  But I'm suggesting having something like a "Hide all Conversations" button or checkboxes to select a particular conversation to be deleted, hidden, or opted out of. I know that opting out and deleting is a bad idea for the sake of training the model.
