Thanks Harald, love it!

Seems to work with clangd too if you want to add it to the list of
supported servers. Let me know if you want me to test something
specific.

How about an option to unfold the tree by default? I was testing on a
small project, probably it gets quite bigger on large projects and
it's better to leave it folded?

Not sure if it's a clangd thing, I noticed that when I request the call
hierarchy on anything other than a function call or declaration I get a
"Error running timer: (args-out-of-range [] 0)". Maybe it could be
handled more nicely? Not sure it's something to notify the user about,
guess silently doing nothing would be fine.

Also, when I get to a leaf in the tree it shows with the '+' prefix,
when expanded it becomes '-' but there is nothing to expand so it just
changes the prefix. Maybe the leaf nodes should be made non-expandable?
