Um im datepicker mit dem kleinsten Tag anzufangen, muss in der jquery-ui.min.js folgendes ersetzt werden:
this.maxRows=(.),(.)=this._daylightSavingAdjust
durch 
this.maxRows=\1,\2=this._get\(arguments\[0\],"calendarStart"\) ? this._get\(arguments\[0\],"calendarStart"\).call\(this\) : this._daylightSavingAdjust

Um submenus zu schliessen, muss folgender patch rein:

mouseleave: "collapseAll",
durch
mouseleave:function(event){this.collapseAll(event,true)},
