Add Content to Top of Region in IPE?

I would personally prefer that the add content button be at the bottom, where it is in the original. It was, however, your initial design that placed it at the top, which sdboyer implemented. I never actually bothered discussing the placement of it, figuring we would refine that over time.

Unless there's any reason to object (would be good to talk to Neca) I propose we move add content to the bottom.

Oh, I would add that for technical reasons, adding content to the bottom is slightly easier than to the top, because everything is kept as a list.

Somehow I expected that would be a lot harder.

In the future this probably needs to be switchable somewhere, because I also just committed a patch that makes the position of the control themable. So presumably something should also be able to switch where the pane gets added to match.

Sorry for opening this again but I am trying to change this option for Panels version 7.x - 3.4 (2014-Feb-12).

I cannot find the related function (ajax_command_append) on /panels/panels_ipe/plugins/display_renderers/panels_renderer_ipe.class.php.

Thanks a lot for any help.

Finally, I found out that I had to change codes on /panels/panels_ipe/js/panels_ipe.js around line 395. Attaching my codes.
Comments with capital letters are for these changes.

Drupal.ajax.prototype.commands.insertNewPane = function(ajax, data, status) {
    IPEContainerSelector = '#panels-ipe-regionid-' + data.regionId + ' div.panels-ipe-sort-container';
    //firstPaneSelector = IPEContainerSelector + ' div.panels-ipe-portlet-wrapper:first';
    // LAST CHILD OF THE LIST
     lastPaneSelector = IPEContainerSelector + ' div.panels-ipe-portlet-wrapper:last';
    // Insert the new pane AFTER the LAST existing pane in the region, if
    // any.
    if ($(lastPaneSelector).length) {
      insertData = {
        'method': 'after',
        'selector': lastPaneSelector,
        'data': data.renderedPane,
        'settings': null
      }
      Drupal.ajax.prototype.commands.insert(ajax, insertData, status);
    }
    // Else, insert it as a first child of the container. Doing so might fall
    // outside of the wrapping markup for the style, but it's the best we can
    // do.
    else {
      insertData = {
        'method': 'prepend',
        'selector': IPEContainerSelector,
        'data': data.renderedPane,
        'settings': null
      }
      Drupal.ajax.prototype.commands.insert(ajax, insertData, status);
    }
    
    // ADD SOME BASIC SCROLL TO THE ADDED PANE
    $('html, body').animate({
        scrollTop: $(lastPaneSelector).offset().top
    }, 2000);
  };
