Essential features for supabase schem visualizer.

Here is a list of what I would consider required feature for the schema visualizer to be useful for any large or complex schema: (no particular order).
1) Undo Redo functionality.
2) Foreign keys point to a random column in the target table, it should point to the primary key (and/or be configurable).
3) Relations connect to a random side of the column, it should be the nearest (facing) sides (and/or be configurable).
4) Allow the reordering of columns.
5) Toggle table or relations visibility.
