Hidden interface controls that affect usability

Only tangentially related, and a seemingly lost old-man battle: stop hiding my scrollbar.

Interesting article. Some points I didn't quite agree entirely with. There's a cost and practically limitation to some things (like a physical knob in a car for zooming in and out on a map - although that was probably just an example of intuitive use).

I just recently switched a toggle on a newly installed app that did the opposite of what it was labelled - I thought the label represented the current state, but it represented the state it would switch to if toggled. It became obvious once changed, but that seems the least helpful execution.

I can't recall the app but it was a similar toggle with a label, when you flipped the toggle the label lit up green indicating it was turned on. But the default state was off but how would you know?

The green / red is at least a half decent indicator (questionable for the colour blind folks though), but the current trend of very slightly different shades of grey is the pinnacle of utterly fucking stupid design; perfect for a non-interactive set piece in a gallery, just dumb for use for by human beings.
