next setp , will add a feature of cumstom Armature modifier with bone correction , no need any extra bones for correction
Thanks a lot, mate 
Looking forward to the custom armature modifier with bone correction. You are doing awesome work!!
Is there a way to turn off and on the blue and red lines when I press the play button?
Also, any chance you could pls have a English version for the Debug part of the UI? 
I have English selected in the addon preferences window.
It seems a lot of changes have been made to how to set the rigs up in the latest version. I am trying to follow this and the results are not the same:
Only F shortcut works to move the bones, the other shortcuts do not work.
I also notice if I just want to move the bones on the x or y axis. That isn’t possible. It just moves anywhere in the 3d space.
Continuing the discussion from ghost_IK (virtual Inverse Kinematics bone/physic bone IK/C++):
Definitely the best add-on if it works. Thanks for sharing. I have tried everything and now it is not working well, probably because the setup method is different from past versions.
That sounds like the same problem that melvi (coincidentally under a very similar username) is talking about.
In past versions, it was possible to specify the direction, but now only the check for SIMPLE exists and the direction cannot be specified. Also, can only select two bones absolutely. Selecting three or more will result in an error. This is a problem that did not occur in past versions.
Also, as a personal request, blender4+ requires an advanced GPU and does not work on my PC,
so I would appreciate it if you could provide a version that works with blender3 in the future.
@melvin (the new version only can select two bones to set as 2ik every time )
a new update for blender 4.20 fix some bugs
