Hi, here is a modification to make the swipe bigger.


Go to Dashboard -> Settings -> Custom CSS and paste this
/*Swipe Button CSS*/
.ReactSwipeButton {
	float: left;
	width: 100%;
	height: 108px;
	position: relative;
}
.ReactSwipeButton,
.ReactSwipeButton * {
	-webkit-touch-callout: none;
	-webkit-user-select: none;
	-khtml-user-select: none;
	-moz-user-select: none;
	-ms-user-select: none;
	user-select: none;
}
.rsbContainer {
	float: left;
	width: 100%;
	height: 100%;
	background: #eee;
	position: relative;
	overflow: hidden;
	box-shadow: inset 2px 2px 4px rgba(0, 0, 0, 0.1);
}
.rsbContainerUnlocked {
	display: none;
}
.rsbcSlider {
	float: left;
	width: 100%;
	position: absolute;
	height: 108px;
	top: 0;
	left: 80px;
	margin-left: -100%;
	background: #0d101d;
	z-index: 100;
	box-shadow: 2px 1px 6px 2px rgba(38, 50, 56, 0.35);
	cursor: pointer;
}
.rsbcSliderText {
	position: absolute;
	top: 0;
	left: 0;
	right: 0;
	line-height: 108px;
	text-align: center;
	color: #fff;
	font-size: 16px;
	font-weight: 500;
}
.rsbcSliderArrow {
	float: left;
	position: absolute;
	transform: translateX(-4px) rotate(45deg);
	border: 3px solid #fff;
	height: 13px;
	width: 13px;
	top: 50%;
	right: 22px;
	margin-top: -6px;
	border-left-color: transparent;
	border-bottom-color: transparent;
	transform-origin: center;
	z-index: 10;
	animation: rsbcSliderArrowAnimate 2s linear infinite;
}
@keyframes rsbcSliderArrowAnimate {
	0% {
		transform: translateX(-4px) rotate(45deg);
	}
	50% {
		transform: translateX(6px) rotate(45deg);
	}
	100% {
		transform: translateX(-4px) rotate(45deg);
	}
}
.rsbcSliderCircle {
	position: absolute;
	right: 0;
	background: #263238;
	top: 0;
	height: 108px;
	width: 50px;
	border-radius: 100%;
}
.rsbcText {
	float: left;
	position: absolute;
	top: 0;
	left: 0;
	right: 0;
	height: 108px;
	line-height: 108px;
	text-align: center;
	color: #fff;
	font-size: 16px;
	font-weight: 500;
}
.slider-bg-color {
	background-color: #18c775;
}
/* END Swipe Button CSS*/
Finished! To change the size, replace "108px" everywhere with the size you want. (original 58px)
Bonus, here is a code that @wpradobr shared in a comment to "lift" the swipe

.delivery-action {
position: fixed;
width: 100%;
bottom: 45px;
z-index: 99;
}
.location-error {
bottom: 0.0rem !important;
background-color: #222b45;
}
