Fred Jan,
Attached are diffs between l2ork coll.c (threaded option and another feature that is currently missing in Pd implementation but is present in Max) and another small bug-fix inside curve.c. There are more changes to Scope.c and comment.c but given these are gui based they are not going to be universally compatible (e.g. vanilla does not have accelerated displace with tag so that part is pointless unless there is interest in ifdef-ing the code.
If you can merge two patches, this will make it easier for pd-l2ork to keep your code as a submodule (assuming you have a git for your code).
Best,
Ico
