Add a floating value label near the cursor while dragging a knob, giving immediate feedback without altering slider behaviour. Inherit SettableTooltipClient on ToggleButton so setTooltip works consistently with knobs and combos. Introduce a shared layout constants namespace in PluginEditor so every panel, row and control position derives from one spacing system. Add tooltips to all knobs, combos, toggles, and buttons. Add Tab/Shift+Tab tab cycling via keyPressed, with a TooltipWindow for hover hints.
