slides

should be replicated for sequencing, so that presenters need not page backwards and forth through an enormous deck, muttering "i know the slide is in here somewhere...ah! here it is...no, i guess that's not it. well, i'll just talk through it," all the livelong day.

back/forth navigation buttons on sequential web content

should be locked in the same absolute location within the window, so that different-sized content doesn't make the user have to refocus on the navigation to proceed with the sequence. and while i'm here, to the power-washers stripping the paint off the building next door who are starting up the compressor now, at 5.45am EST: who do you think will be first against the wall when i am king, etc?

jars containing fluids or suspensions

of any viscosity will be required to have wide mouths and no shoulders, such that never again will anyone be late for an early meeting because the last droplets of honey were trapped in the rounded shoulder of the honey jar, beyond the reach of even the bendiest spoon.
