Is there a solution which would allow me to open links in the "correct" browser window? This would include allowing me to define url patterns and map them to the correct browser profile (window).
Or maybe you can script it at the OS shortcut level, making a URL handler script that captures all https links and then does a regex on them to decide which Chrome profile to launch. Note that the Chrome command-line to open a specific profile seems to change every so often, so not sure which of these is current, but hopefully one of them still works... https://superuser.com/questions/377186/how-do-i-start-chrome...
Now I just need the same thing for Linux.
