Can a method be added to make selected objects into a sub patch that automatically adds [inlets] and [outlets] and retains all cord connections?
Ideally this should keep the internal states of objects and avoid glitches.
You seem to have CSS turned off.
Please don't fill out this field.
implemented in the patcherize plugin of punish (it's currently keeping the internal state of the patcherized obects, but this leads to some weirdness with GUI objects, so it will most likely be removed in the future)
closing this as it has been implemented (though as an external and not as part of Pd-vanilla)
