[FEATURE] Add support for panes too

[Borwe]

I was wondering if there was any plans to add support for scrolling through panes too.

I hadn't considered that, how do you imagine that fitting into the UI of this thing?

I've think you listen for when new tabs are open, and then add handle that, was thinking that then it could also listen for panes opened, I believe there is a similar event to the tabs one available.
