Exit Settings dialog with Esc key
This is probably just an oversight, when you are in the Settings dialog the only way to exit it is either by clicking on the X button, or by Alt+F4, none of which are the expected method of exiting a dialog for power users, Settings was the first thing I opened after installing the browser, and I was actually quite surprised that Esc didn't work. I believe Esc is the expected hotkey and should be added to the list.
i was going to say that that might make it hard to assign the Escape key to any commands, but that's pretty much impossible anyway. If I delete the default key for "Stop loading" I still cannot assign Esc to something else.
This was annoying me too, I didn't find a solution.
HOWEVER Using the setting : "Open the settings in a new tab" , and then pinning the tab did the trick for me!
I know not a solution, but a temporary workaround
