I know I'm getting a tiny bit off topic, but I just had a go at doing the

It's actually surprisingly hard, this is too hacky to ever merge.
You can tell you have an instance already open, and you get told the DBus
path for that existing instance, but there's no way to tell which
activities that main window is on without then resorting to grabbing winIDs
and probing X properties.
BUT, a user made a nice point about why the current behaviour is wrong

A long time ago, we decided that out of the following options, the<br>
