Indeed.
Most of the times, these dynamic things on web pages and elsewhere mispredict what I actually want.
No Google, I did not want to zoom in on the map that you automatically did for me. Rather I unzoomed back and you automatically zoomed back in.
No scroll bars, I don't want you to disappear or even thin down automatically.
I personally don't like infinite scrolling as a solution either as it messes up scroll bar operation.
And I want strictly none of the above if when clicking 'back', you don't take me to the exact same view I was on before, without the elements of page jumping for a few seconds.
No my laptop and phone, I do not want you to wake up when I disconnect power, and especially so when I had just put you to sleep!
Glad that Wikipedia is planning to show and hide the side panel on user instruction/click. Please keep it that way.
