I'm happy to spend 5mn improving the > GUI :-) I'd say add an extra horizontal split in the second column, so you'd get three areas in the right column: - top for the global target (permanently) - middle for current, either: - "current most lagging" if "Global" is selected in left column - selected process if a specific target is selected in left column - bottom for backtrace Maybe with that setup "Global" in the left column should be renamed to something like "Dynamic". The backtrace area would show selection from either top or middle areas (so selecting a cause in top or middle area should unselect causes in the other).
