Please add "show class hierarchy" option to code editor

When I right click on a type in source file then I have option "Find Usage", which is a great option. However the following option would also be useful:
"Show class hierarchy" or just "Hierarchy" which would show inheritance tree for a class. It could also be extended to show not only parents, but child classes as well. However showing child maybe could be a separate option. Find result could be displayed even in the same window as "Search Results". Above options would speed up understanding a new source code and easy browsing code in a bunch of classes.
