11:49:27osunescottj: thanks that did the trick, tried a few minutes ago (kill-group group to-group) but it kept the group open/alive
11:49:43scottjosune: I'm not seeing a function destroy-group
11:50:57osunescottj: found it via slime autocompletion but now looking at the source code it's not there
11:55:06osuneanother question, when dumping a frame/group layout, the slots :windows / :current are not nil but window ids. is it save to keep them there when restoring (eg. via restore-group) or should i set these slots to nil ?
