You can create customized graphics to be used as panel end marks when you customize LR Classic. I have created customized graphics files to remind me of my color tag assignments anddirectory structure for cataloging my files so that I can remain consistent as I move forward . I also have a need for reminders on customized shortcut key assignments or other hints that may help me. Currently you can assign only one graphic and it shows up in both the Right panel end mark slot and the left end mark slot. I would like to have the ability to have a left panel end mark (with one set of info) and the right end mark with a different set of info. Seems like a wasted space and wasted opportunity to have them both the same.
