Minor bug/request: If the Search & Replace window is minimised, then it should be restored when you press Ctrl+F.
Request: Could Ctrl+H also bring up that window? That's the standard Replace hotkey.
Request 2: An option to expand variable references. So if you're looking for "Foo" and a field in an action has the value %sport%, and sport contains "Football", that action would be found. That would be incredibly useful for tracking down file locations, like "Why did my build try and access the Z drive". Since almost all my file locations are stored in variables, and you can't search variables directly, it can be tricky to find them.
Praise: The search/replace window works really, really well. It's probably the best I've seen for a non-text-editor program.
