This is very very minor but because of a reflect of mine I notice it all the time.
When you’re scrolling down a thread on mobile, you get a handy shortcut back to the threads tag at the top.
Perfect for returning to the tag once I’m done to read some other threads!
But when I get to the bottom of a thread and decide to return to the tag, I have an automatic reflex: scroll up. Probably this is because on many sites the back button is on a non fixed header up there.
Every time I realize within moments that the shortcut is actually always at the top already but now, suddenly, it’s gone!
And it actually doesn’t return until you start scrolling down again.
Not sure if this is by design, and it’s like… The least important thing in the world, I just can’t stop being thwarted by it every time.
