1) Can you please add a predefined scope of "All open tabs" to the various search dialogs. This could be a very useful search scope, since a user will typically have "related" files (or files relevant to the task at hand) open in the multiple editor tabs. But such a scope does not appear to be one that a user could custom define.
2) If possible, an additional predefined scope of "all visible panes" when using split panes would be useful as well.
p.s. I love the new Find UI introduced in 7241
