Use case - Try to change the text in this Webflow project:
You have multiple elements stacked on-top of each other, and one of them (not on the top of the stack) is a text element.
If you'll try to change the text while Auto-Select is activated, you'll see that it's impossible - as double clicking on the element causes Auto-Select to select the element on the top of the stack.
Even if you'll use the project's tree to select the text element, and then double click on it, Auto-Select will still override your selection.
Allot of graphic design programs have the option to disable auto-select.
Pixelmator for example made it real easy by putting the option in the right click panel:
I've tackled this problem too many times to count,
