Make Connectors always stick to their sticky notes
If sticky notes are placed in a table and the table is resized, the sticky notes change their relative position in this table othe than the connectors between them.
In the result the connection is getting lost.
Same thing when a group of sticky notes ist resized all together, f. ex. in order to make them all the same size.
The loss of this connections ist most annoying, sometimes it is recognized far later on, when it is to late for an undo operation.
