open default/first group?

[bjlockie]

Is there a way to open/expand a default/the first group when the extension button is pressed?

There isn't, as far as I know, and I'm not sure why you would want to expand the first group while the current group may not necessarily be the first.

However, you can press the right-arrow keyboard shortcut to jump to the current group in the list, which is probably what you're looking for.
