AFAIK Joakim leaves the responsibility to set the group parameter to the application (ECB). I make Emacs responsible for keeping track of groups. To me this means two things: (1) Groups should conform to internal windows. Klaus Berndl told me that this is the case for ECB's edit area. (2) `split-window' should be the single interface for creating groups. > An obvious difference is that his proposal allows groups that do not > form a rectangle (e.g. ECB could use a group for all the windows around > the editing area). Even for rectangles the case is not entirely clear. In the following four windows frame ----- | | | |--+--| | | | ----- we know well that the internal windows differ according to how the first split was executed. If the first `split-window' did not have GROUP set to t and the subsequent ones did there are either two vertically aligned groups or two horizontally aligned one. The situation becomes much more complicated when groups may comprise arbitrary windows of a frame - just think of cloning such a group. More problems will arise as soon as two different applications will attempt to manage their private groups simultaneously in the same Emacs session.
