Did you know that you can create your own custom end panel icon to use with Lightroom? Simply create your graphic (using Photoshop or Illustrator), and save it as a .png. Then, in Lightroom, choose Preferences > Interface > Panels. Under the End Marks area, select Go To Panel End Marks Folder. Using the operating system, place your graphic file in the Panel End Marks Folder. Then, close the preferences and return to them – you will see your graphic at the bottom of the list. Select the graphic to display it at the end of each set of panels.
Note: you can also save the file as a PSD file or JPEG however the JPEG file will not support transparency.
