Use case & Proposal

"onReorderStart" detects that a reorder has started.

A list may contain images or a lot of text information.
We want to make it easy for the user to reorder the list by omitting some information.
For this reason, it would be nice to have a trigger at the start of sorting.
It would also be nice to know what was sorted (or grabbed) in order to make it scalable.

"onReorderEnd" detects that the reorder has ended.

This allows the data storage process to take place
Saving the data for each reorder is a waste of time, as it requires multiple communications.

In order to make it possible to save the data in a single operation, we need an event to detect the end of the operation.
