Requested change

Some considerations:

Given that there is a new goal of reducing the complexity in this repository to make it more accessible to open for contributions. It is worth to explore alternative libraries that make the use of drag and drop a bit more intuitive and with less boilerplate, and that can support both desktop and touch screens without to much extra effort.

Current library would need an additional separate implementation for the touch screen and perhaps have some "smart" detection to know which one to use.

Alternative implementation with react-beautiful-dnd is available here https://codebar.github.io/pairing-tool/?useNewDragAndDrop=true

Hmm, I wasn't able to upload the csv file on the tablet, I could choose the file but then when I tapped on it nothing was happening, let's see if someone else can manage to upload it.
