I found this
https://support.advancedcustomfields.com/forums/topic/how-to-create-repeater-field-up-and-down-buttons/#post-162165
But there was no support on it so I would like to make an official request.
When my repeater block item has many fields in it, it makes the item block very large and making it very difficult to re-arrange them by drag and drop only. Many times I have to zoom far out from the browser to make it work. This is extremely relevant with using ACF to create gutenberg blocks as the edit section of the preview block is very limited.
It would be awesome if when hovering over the drag and drop area that if the block is over [xxx]px tall then up and down buttons appear near the top and bottom of the drag and drop area. Clicking on them just moves the block up or down one spot accordingly.
If the item block height is not that tall then it might not make sense to show or need the buttons as there may not be enough room for them.
Thanks

If anyone knows or has a snippet of code to add that adds this support, then please let me know. Thanks
