Changes between Initial Version and Version 1 of Ticket #36447, comment 3

initial	v1
3	3	You should know what an icon/button does BEFORE you click it. If I'm using an interface and I don't know what a particular button does, I'm less likely to click it at all, just in case it messes up my work. If I don't know what the icon/button does, how do I know if it's non-destructive?

5	6	Even though the sizes may be arbitrary, they'd still benefit from having labels like "Mobile view/Tablet view/Desktop view", or something along those lines. They're not device specific and will at least give people an idea of what the icon does.

	8	Also, tooltips don't become distracting once you know what an icon/button does. I refer to the Visual Editor again. I don't find the tooltips on any of those buttons annoying and I've been using them for 10+ years. Once you know what an icon does, you simply click it and move on. Your mouse doesn't tend to hover over it. The tooltip will only display for a microsecond.
