1. Run macro
2. press 'a' key
3. navigational pop-up appears
4. choose a sphere that represents a certain workbench
Result: workbench opens
Here is a screencast of it in action:
Here is the macro:

1) Display all available workbenches as spheres with their respective logos
2) When hovering over a specific workbench sphere that it will immediately vanish all the other spheres and open the commands of that said workbench in separate discrete spheres to choose from.
Result: time-saving travel time going back and forth from the toolbars to the canvas
Any pyside-nistas available to help ?
