God forbid somebody clicks the button called "Save" thinking that it would save the file, rather than deciphering the icon to determine that the button labeled "Save" is actually "Share". Why not rename this (https://0x0.st/zKfv.png) menu entry to "save" too while they're at it? And why is that the only button with text in it? The others have tool tips, but otherwise they're just bare icons. The only one with text is the share button that says "Save".
It's indefensible. It should have never made it past code review, let alone stuck around for several revisions. If the button had said "Share" instead of "Save", there never would have been any complaints about it.
Your explanation sounds reasonable.
Has been bitten before by an open source (I think) program that was for taking screenshots but that forget to mention it would also, by default, upload them.
Be very cautious when working with new software in sensitive settings.
With https://cliperado.com we go a step further. It will keep your screenshots up to date for you, and notify you of any changes. We created it to keep our step by step screenshot guides updated with every deploy.
Super useful feature. Will miss it.
