not sure you if can do like "view->new view" programatically, maybe possible but i do'nt know how. Workaround that i do know : having your main patch with subpatchers in tabs (it can be one subpatch) and you send a "front" message to [thispatcher] in this tab, it brings a new view of the tab to front as a separate patcher window. ("it's not a bug, it's a fature"...)
