Lightroom End Marks

Marcin Wichary:

The search for the strangest Adobe setting continues in Lightroom, where the first option in the Interface section is… end marks[…]

Presently, only one option is there… …but at least back in 2012 there were many more.

What does it do? It adds an old-time’y glyph at the end of either left or right panel.

This is the very first interface setting shown in the preferences window. I guess the idea is that you might want a way to know you’re at the bottom of the list of panels. But the weird thing is that Lightroom does show scroll bars for the panels, even when System Settings is set to hide them, so I can already tell whether I’m at the bottom by looking at the scroll thumb.

John Beardsworth:

These Panel End Marks are simply png files stored in the Panel End Marks settings folder and you can easily create your own in Photoshop.

I love his idea of repurposing them to “serve as a reminder of star ratings, colour labels and even keyboard shortcuts for flags.” I wish more apps had places to attach user comments, either to model objects or to bits of UI.

"I wish more apps had places to attach user comments, either to model objects or to bits of UI."

Me too.

I've been kicking around an idea for a personal web proxy that would provide persistent annotations to sites (think sticky notes you stick on whatever you browse, but it would go deeper than that).

But I think what I really want is that for local applications. I get the feeling that building on top of Apple Events at this point is risky - it seems fundamentally at odds with sandboxing, and I know which one of those will win.

But I love the idea.


That's another thing that's super neat about web apps and makes them preferable to native apps: it's trivial to make changes to the UI using tools like Violentmonkey, and even add new features or automations. Every web app I use regularly has extensive changes: hiding sections I don't need, rearranging UI elements, buttons triggering JS code that does full tasks, usage notes, and so on.
