Not that I've been able to find...
Btw, here's the code you asked for, to close the size overlay by page tap (I couldn't get my general function working):
Code:
kbook.model.container.sandbox.SIZE_OVERLAY_GROUP.sandbox.VIEW.sandbox.SIZE_OVERLAY.sandbox.canTap = function () {
return true;
}
kbook.model.container.sandbox.SIZE_OVERLAY_GROUP.sandbox.VIEW.sandbox.SIZE_OVERLAY.sandbox.doTap = function (x, y) {
if (y < this.height - 128) this.getModel().closeCurrentOverlay();
}
You can put this in any addon, and it'll work. I don't think I'm going to add it as an option.
