There was a need to open Current Navigation, a.k.a Quick Launch links in new browser window, when being on a front page of a specific section of the SharePoint portal.
Again, jQuery provides us an easy way to achieve this without having to create custom Navigation controls or providers and whatnot. Please note that this requirement (and solution) assumes that all subsites are visible in Current Navigation. By default, Current Navigation shows two levels of subsites. If there would be more, navigating to third level subsites would not be convenient unless Current Navigation was configured to show at least 3 static levels.
var isWorkspaces = false;
if(window.location.href.toLowerCase().indexOf('https://myintranet.sharepoint.com/workspaces/sitepages/home.aspx') > -1)
isWorkspaces = true;
// Open left navigation in new window only when in Workspaces section
$("#s4-leftpanel-content .ms-quicklaunch-navmgr a").attr("target", "_blank");
