Hi Danny,

> picking and finding all the edges, and you always miss that tiny edge,

For now at least, this particular stage can be simplified by using Ctrl+A (or in the side pane, the Select / Sel All button).

If you have an edge currently selected, then select all will go through and select all other edges on that same object, and when you have edges selected it will not go through and select other regular objects.

That will be guaranteed to catch all edges of a surface, including tiny ones.
