Fix/lock toolbar (avoid unintentional undocking)
Please add a feature to avoid undocking the toolbar. The Selection Tool (black arrow) is too near to the dotted line, indicating the draggable region of the toolbar. I've accidentally undocked the bar countless times. I mean hundred and hundred of times of cumbersomely dragging the toolbar back where it belongs. Especially when working fast on a big screen or multiscreen setup.
A suitable workaround is using keyboard shortcuts, but that's not a good solution for a UI flaw.
