hi,
i've got some code in ucw which creates an emacs buffer (sample attached) with loads of information from a backtrace. it becomes a lot more readable when you look at the buffer after M-x occur RET ^--- RET.
this is not a development tool per-se, but it can be helpfull for communicating problems to/from a user and a developer. is something like this worth adding to slime or would it just be bloat? if so, is there some way it could be made more useful outside of ucw?
