in many cases stock moves can not be deleted

When you validate an entry picking there is no way to cancel it. There
is no button to do it.

Imaging you receive material directly without any order, you validate
it, and after validating you push create the invoice. You didn't realize
that invoicing was set from order not from picking.

There is no way to come back. No way cancelling entry, No way invoicing
entry. It would be very usefull having the possibility of changing
status of picking to "to invoice" before or after validating it or
cancelling / deleting inventory entries in order to go back the picking
and "re validating" again after changing status.

This would be a wishlist.

Thank you very much.
