Sometimes I like it that sidekick shows me the current buffer, even when I switch editpanes. Other times, I only want sidekick to show me what is in one editpane, and not the other (s).
Some kind of option perhaps that says "Do not change sidekick when a different splitpane is selected", so that if SideKick gets buffer changing messages on other EditPanes, and sidekick has parsed the correct buffer, they are simply ignored.
If you explicitly parse a buffer while in a different editpane, then that editpane becomes the "sticky" pane for sidekick in the future.
