Also, I've reached a stumbling block when trying to improve my placeHook function. It currently acts on the WindowSet obtained by 'gets windowset', and simply returns 'Endo id'. The reason for this is obvious: It needs to do stateful stuff (namely get and set window positions at the X11 level), and there's no way I can fit that in a function (f :: WindowSet -> WindowSet).
Which issues did you run into in trying to manipulate the WindowSet in placing floating windows? I think that you can avoid the call to moveWindow by updating the Data.Map.Map in the WindowSet to respect the new position. If that works, then hopefully those questionable alternatives you suggested might not be necessary. Adam
