So this got way more complicated than I thought real fast, but got done
in the end anyway.
- rclick / mclick don't activate the anchorClicked event, only lclick
- ok, so use Ctrl-lclick to close, but
- anchorClicked doesn't know the keyboard modifiers like a regular
event, only the url
- so change the script (new version below) to track modifiers
separately
- but closing the overview window still leaves the top level
window with a placeholder in it, so I had to modify
nested_splitter, new version pushed to launchpad / available
in snap-shot tomorrow
