In xmonad she standard behaviour of windows is that they are tiled. One can change this, if one uses for example xprop | grep WM_CLASS and puts something like this:
myManageHook = composeAll [ className =? "MPlayer" --> doFloat , className =? "Gimp" --> doFloat]
Then the windows of those programs float and have a "natural size" (as they would appear e.g. in gnome).
Now my question is the following: Is it possible to do this "on the fly"?
I can click and drag it with the mod-button1 held down and then resize it manually. However, it should resize automatically to it's "natural size". What can I change in my xmonad.hs to achieve this?
Another possibility (which would be sufficient for me) would be to have some "starter script", lets call it xms: If I type
xms foo the program foo is started floated and its windows have "natural size".
