Because after studying the code it looked
like a difficult thing to pull off. This is because the regular displacefn is
used for initial posting of objects which is absolute in nature while
displacewithtag is relative, so the two don’t play very nice.

Hey Ico,
What not just use the displacefn to do the move with tags? Then
we wouldn't need to change that core struct.

The said changes are in
pre-git tarballs. I think they are also listed in the changelog under a
specific date which should make things a bit easier to isolate. That said,
implementation alters widgetbehavior struct by adding one more entry and as
such it breaks compatibility with gridflow unless recompiled from scratch using
the new .h file. Even then there might be other incompatibilities. That said,
I've encountered none, other than gridflow. Of course, other externals need to
be recompiled as well (but no changes to their source are required).

Hey Ico,
That's great, we need to do a lot more of that. Can you point me
to where these changes are so I can check them out?

Indeed, pd-l2ork moves
entire selection by tag, so instead of redrawing everything, out issues single
tcl/tk command. The only thing that still redrawed every time when displaced is

I believe Ivica made such a modification in Pd-l2ork-- whatever the case, moving many iemguis in
Pd-l2ork is much snappier than in Vanilla or Pd-extended. But I haven't measured the cpu load.
