unfortunately not entirely (i could only test the git version (rev: bb91ad26e16), due to my bad internet connection).
i still get a tcl error, when trying to change the number of items of an [hradio] in a closed subpatch [1].
see attached patch that illustrates the problem.
it would be great if this minor annoyance could somehow be fixed.
You may want to try out pd-l2ork's version of iemgui objects that in addition to offering resize/move hooks also take care of unnecessary redraws. I suspect merging those source files with core pd should be relatively seamless as they've been for the most part edited as independent entities.
Cheers!
