Physical asset editor needs way to lock bones/bodies in list

When working with contraints you often have to jump between bones and the bone tree list often returns to the top, most of the time you can’t really fix it on the part of the skeleton you want to see. The graph window is also no big help, a body with lots of contraints is hard to read and it changes focus when you click a bone accidentally.
Make a window where you can manually fix a number of bones/bodies with the data from the skeleton tree so that you can easily select bodies/contraints for editing
