frimical: I'm the guy that changed flwm to have a more conventional layout (titles on top). I've thought about adding a "maximize in both directions" button, but I hesitated because:
1) Having five buttons will make the window look more complex, while only saving one mouse click
2) Maximizing in both directions will cover up the wbar area at the bottom of the screen, which many people would not want to happen
3) It will make the flwm executable slightly bigger
4) Other window managers like jwm offer such a maximize button, so people can install one of those if it is really important to them.
So I don't expect that we will implement this as part of TC base. Maybe a "flwm delux" could be made in the future with this kind of button, or at least an option to turn it on. But I have other projects I want to work on first.
