Is there a way to change gestures? - eviltoast

I keep trying to swipe right to return to my feed after viewing a post (a setting I implemented on Apollo). Sometimes it works but the majority of the time I wind up upvoting a post. My thumb is too short to reach all the way to the top of my phone screen to click the back button with one hand lol. (Phone developers: bigger isn’t always better for women with small hands!). Any ideas?
