Probe scanner window in Photon:
Probe scanner in the old UI:
The old UI does a much better job at telling you what is going on with your probes, makes it easier to recall them, makes it easier to understand information and see it and buttons are much easier to see and use. Photon removes button design, hides information and makes very a important button not only not look like a button but also makes it much smaller. Old UI is better than Photon here.
