The best thing the crypto industry coined might have been the expression “rug pull,” but I’m not happy about that. To me, it perfectly describes how it feels when an app or a website randomly changes your scroll position for no rhyme or reason.

You’ve seen it so many times before:

• you start reading a webpage, but it throws you back to the top when JavaScript finishes loading,
• you start reading a webpage, and ads or other stuff appear and shove you around up and down,
• you press a back button and that goes to the previous page… but to its top, rather than where you actually were,
• you zoom in or out, the position isn’t recalculated properly, and suddenly you see a different part of the page and lose your orientation.

To me, the scroll position is as sacred as the mouse pointer position, given the two are related whether Scroll Lock is around or not: one is you, the other is the world around you.

But there are moments when software scrolling with the user or even for the user is appropriate, and here’s one example:

When you switch tabs, the content below should always scroll to the top, but it doesn’t here.

Here’s an even worse example, also from Settings:

Why should the content scroll to the top here? Because in these situations, the fact that the content container gets reused is just a technical quirk of the implementation. From the user’s perspective, this is all new content, and new content should always start at the top. Otherwise, things will get confusing really fast; imagine it especially in the default configuration without scrollbars, where you might assume result number 6 is the first result, or completely miss the most important, topmost options.

(Before you ask: Yes, I also see this in Tahoe.)
