I completely agree. Emacs should not be enhanced to support especially
ECB but it should be enhanced in that way so a tool *like* ECB (not
exactly ECB) could be implemented without that heavy advice-stuff
currently needed by ECB.

and IMHO the discussion between Martin and me goes in this direction 
(at least this is my intention ;-): I do not want all special stuff
of ECB into the c-core of Emacs but Emacs should offer a well defined
interface to allow tools like ECB introducing a smart window-layout-
engine as needed by IDE-functionality

For this some window-pining and -grouping is needed as suggested by
Joakim (this is nothing special for ECB but can be very useful for
other tools too - maybe speedbar)

Then a mechanism is needed to display certain buffers in certain windows.
For this porting display-buffer to elisp is a great step forward.

Also very helpful could be to save not only the window-configuration of the
whole frame but also to save and restore the current subwindow-configuration
of a certain window - i do not know if window-tree already supports that
somehow?!

Eric, do we agree with that?
