     <session> l9:currentSub ?sub is the URI of the sub we're tied to for displaying and
     editing. If we don't have a currentSub, then we're actually
     editing a session-local sub called <session> l9:currentSub <sessionLocalSub>
     UI actions:
     - drag a sub uri on here to make it the one we're editing
     - button to clear the currentSub (putting it back to
       sessionLocalSub, and also resetting sessionLocalSub to be empty
       again)
     - drag the sub uri off of here to send it to another receiver, but
       session local sub is not easily addressable elsewhere
     - make a new sub: transfers the current data (from a shared sub or
       from the local one) to the new sub. If you're on a local sub,
       the new sub is named automatically, ideally something brief,
       pretty distinct, readable, and based on the lights that are
       on. If you're on a named sub, the new one starts with a
       'namedsub 2' style name. The uri can also be with a '2' suffix,
       although maybe that will be stupid. If you change the name
       before anyone knows about this uri, we could update the current
       sub's uri to a slug of the new label.
     - rename this sub: not available if you're on a local sub. Sets
       the label of a named sub. Might update the uri of the named sub
       if it's new enough that no one else would have that uri. Not
       sure where we measure that 'new enough' value. Maybe track if
       the sub has 'never been dragged out of this subcomposer
       session'? But subs will also show up in other viewers and
       finders.
