Eclipse: Nested Editor Tabs?

Question

Is anyone aware of any method (or external plugin) that would allow for nested editor tabs? It would be nice to be able to group related open files into their own "master" tabs, but I'm not sure if this is even possible. Any ideas?

Answer 1

This is totally non-obvious, and I discovered it by accident, but...

If you click on a tab and start dragging it downwards, once you get more than half-way down the editor pane, a horizontal line will appear. Let go, and now you'll have two different editor panes, each with tabs of documents. Now you can drag tabs up and down between the two panes to see different documents at the same time.

I think that's as close as you can get.

Answer 2

I think the best you can currently do is "Window->New Window" and then use each new window as a separate "tab" of related editors. Not exactly ideal, I admit.

It's a cool idea though, especially if you could have shortcuts or something that open groups of editors with a single command.
