I curently don't kown :

• how removing an (obj/msg/etc..) in a patch.
• how unconnecting (obj/msg/etc..)
• how showing or hiding a sub patch
• what it's possible to do and what's is not...

there is still no possibility to remove obj/msg/connections (as far as i know)

sending the sub-patch a "vis 1" will make it pop-up, "vis 0" will make it disappear again something like:
