One of the programs I use at work had an overhaul recently. I wanted to find some notes from a previous day and couldn't figure out how. I asked someone to help and they told me to click some symbol in the corner of the page. I didn't even know it was supposed to be a button, hovering over it doesn't say what it does. It looked kind of like [ iii ] which tells me absolutely nothing about its functionality.

The overhaul was supposed to make things easier.
