Hmm, could i write a feature-request for this? ;-) > > I'm curious to know what you need it for, Could be needed by tools like ECB which uses tree-buffers. ECB currently does a very smart recentering of a tree-buffer, so always a maximum of useful informations are visible, e.g. as many subnodes as possible if a node is expanded. ECB can currently use `count-screen-lines' for this and this works perfect except for some very seldom (or almost pathological ;-) cases.... But nevertheless such a function would help to write the code even better working perfectly for all cases.
