Hello Peter A hint, but not yet the solution World griddingOnOff. toggles the grid for morphs. World setGridSpec. Allows to set the grid. World griddingOn tells if the grid is on or off The commands above affect morphs, Morph new openInWorld but not the windows (Nautilus, Playground, ..., SystemWindow, ...) Something else in addition seems to be needed ...... Regards Hannes On 8/28/17, Peter Uhnák <i.uhnak@gmail.com> wrote:

Hi,

is it possible to somehow "constraint" the movement of windows (Nautilus, Playground, ..., SystemWindow, ...)?

E.g. I want for them to only move (or "snap") only at steps of e.g. 20 pixels.

So sort of snap-to-20-pixel-grid behavior.

Thanks, Peter
