Switch Toolbar Tabs During Click+Drag
Clicking and dragging across tabs within a toolbar switches to each tab as your mouse reaches it so long as the mouse is held down. Once the mouse is released the active tab remains selected.
Example:
1 Click on Tools tab of the toolbar
2 With mouse held down, continue to drag across other tabs, such as Generator or Output
--- Result: Generator or Output become selected, and the related tools become visible
3 Release mouse once you have reached the tab which contains the tool you are looking for.
--- Bonus: If mouse is released over a tool, activate that tool immediately.
