Long List 100+ items

Hi,
There is a significant performance degraded with bigger lists, especially initial load takes a lot of time . can "Legend List" be implemented with sortable for better performance?

Hey @rohankm!

I've been thinking of adding a possibility to sort virtualized list items but it is not that simple. The main problem is that reanimated style updates cannot be synchronized with React renders, thus I won't be able to properly set the style of the item when the list renders with a new array of data items.

I haven't figured out a proper solution for that so I implemented my custom sortable components that don't use virtualization, thus, they won't be performant for long lists of items. I think I should work on the virtualization in the future but it is a bit complex topic to do this right on myself and integrating sortable list items to any of existing lists also doesn't seem to be easy because these synchronization problems that I described above.

What I can suggest is to assume that this library currently is meant to support smaller grids/lists with tens of items but not hundreds or more.
