Cant have been that bad, tron (aka detron) applied a version to SVN. (r538) however it does miss a couple of the additional snapping features mine included for aligning the windows. So ive made an additional patch against r538 with these in it.

Im still waiting for some critisim to the patch however. (eg. thoughts or suggestions (eg. should it allow to snap the moving windows right border to the others right border... I havnt done this as I dont think its used or at least would be to difficul to manage)
Edit: maybe this topic should be moved to the General OpenTTD now? (mods?)
