Indeed these are old nuisances.
In Bongo 2 IK - not user friendly and intuitive I deployed a few ideas regarding the display of IK structures, based upon the graphics I use in my tutorials.
Currently I elaborate a concept towards the developers team, implying the icons to figure as a widget.
The ‘freezing’ depends on the complexity of the model and the speed of the CPU. It can take Bongo a while (to long) to find out that a IK-structure is crooked – I guess this is inevitable. Hopefully the IK developer can find a way of improvement.
I can only agree that the Help file needs improvement. I’ll try to contribute personally.
These are all major issues, not quickly fixed in a SR. As you may have read a Bongo 3.0 is in the pipeline. I’m afraid you’ll have to wait until then.
PS The IK symbols in the Animation manager currently do show their nature (albeit discreetly).
