It's too easy to show the remove button,seems like need some delay animation

First,Im sure this lib is very nice and beautiful.
When I drag an item in the list, the remove button immediately appears. Normally, the remove button should only appear after dragging a certain distance (such as horizontal drag 10 or 20 pixels) to make it more reasonable.
I just want to sort items by dragging them up and down, but when I initially hold down an item, the remove button appears on the right.This could be a little bit confusing for users i think.
Although it's a small issue, I believe it can be improved for better user experience.
thank you very much~
其实是右边的删除按钮太容易就出现了，常规做法是横向有一个拖动触发条件会比较好
