[REQUEST] gesture to close mail and option to show bar at the bottom

please create a possibility in the mail view to close it directly with a swipe down, for example, and return to the folder view. This would be very helpful for one-handed navigation. In addition, an option to change the bar from top to bottom depending on the display size would also be very beneficial

Why would we add a special gesture (that conflicts with scrolling) when you can simply use the back button (or back gesture if you’ve configured Android to use gesture navigation)?

ok, then you just have to work with the buttons. I found the function known from my former mail app to be very functional and intuitive. Back gesture is also in conflict with the page turn function.
What about the option to change the position of the bar? (top/bottom)
