Floating menu swipe trigger area customization or trigger area reduction
I use the floating menu with the corner swipe gesture a lot.. (Swipe right corner) but because it covers the whole right hand said of the screen, if there is a sidebar in an app that opens from the right, triggering it is very difficult. And I always trigger the floating menu instead. In an earlier version before the redesign (a year or two ago) a certain area of the screen's corner was allotted to the floating menu and I could use the part about or below it to trigger other apps side bar/menu functions without the floating menu coming up..
Here's an example:
I agree and just assumed enough people would have the same problem and that it would have been simply eventually changed to more like what you're describing
