As an option: open Chrome in new *window*, not a new tab in existing window
When clicking a link in e.g. Mail, it's horrible to be teleported to a workspace where I have other Chrome windows because Chrome insists on opening new windows in a new tab in a new window. This script used to work (and I was able to make Choosy use it), but now it ends up creating a second instance of Chrome (wow, had no idea that was possible with any Mac app!!). This new instance doesn't have my bookmarks and is not logged into the sites where the "original" chrome instance is logged in. That wasn't a problem before, It may have been a Chrome update that broke it, but I noticed it around the time of a recent update of Choosy...
