src/commands/profile.menuitems.js (add menu items):

  define(function () {
    return {
      profileMenu: [
        {
          signature: 'myext-open-pws',
          name: 'Go to Personal Workspace',
          group: 'others'
        }
      ]
    };
  });

src/commands/open.pws/open.pws.command.js (add a command):

  define([
    'csui/lib/jquery', 'csui/models/command'
  ], function ($, CommandModel) {
    var OpenPWSCommand = CommandModel.extend({
      defaults: { signature: 'myext-open-pws' },
      execute: function (status, options) {
        var deferred = $.Deferred();
        require([
          'csui/models/node/node.model'
        ], function (NodeModel) {
          var context = status.context ||
                        options && options.context;
          var connector = context.getObject('connector');
          var pws = new NodeModel(
            { id: 'volume', type: 142 },
            { connector: connector }
          );
          pws.fetch()
             .then(function () {
               var nextNode = context.getModel('nextNode');
               nextNode.set('id', pws.get('id'));
               deferred.resolve();
             }, deferred.reject);
        }, deferred.reject);
        return deferred.promise();
      }
    });
    return OpenPWSCommand;
  });
