I want to say Thank You to @sufay, who made a marker package by using a set of SharePoint 2010 markers which may be able to help illustrate the map better.

If you have interesting, click here to download it. The below are the steps to add this package into your XMind.

  1. Launch XMind
  2. Go to File > Import
  3. Select Marker Package, and click Next button
  4. In the marker import dialog, browse the download .xmp file, and add into XMind

Now, you can see these markers in your Marker View (View — Markers), or modify them at the Marker Preferences page (Edit — Preferences — MindMap — Markers).
