Patch #7722: no 'Auto IK' for solitary (unconnected) bone
'Auto IK' is a great feature, however when solitary unconnected bone (without connected child bones) is grabbed it can't be moved because of IK. This can be really annoying. Preventing 'Auto IK' for solitary bones would improve user-experience by making mixing of FK and IK more convenient while using 'Auto IK'.
Patch by Teppo Kansala (teppoka).
