A list of all dependencies on selected object

Actually I will correct myself… referring back to issue #27 “Since an object, e.g. a line, can depend on more than one object (like, a line on two points), the pattern graph is more complex than a tree. It’s a cycle-free directed graph.” Not easily solved as currently coded. If it was - tools could use other tools in the future history. Right now the tool dependencies are based on a simple counter - where when a tool used by another tool, it’s reference counter is incremented. If a tool’s …

At least it is possible to show the reference counter…? I can figure out the dependency myself, but it will be helpful to know how many left.
