Well, living with a Maffia boss makes you adapt, you know. A “He’s so nice when he’s sober” kind of deal 
It just destroyed th worflow for the ones who thought it was “Brilliant” to put it back.
Open the toolbox at the right side of the screen and there no place for it so it moved to the left.
This led to me selecting the wrong tool when all I wanted to do was to do a fast click to select the default arrow tool.
But you knew that …
Actually, rather than putting an option in Preferences, I would rather see a fully featured mouse/tool set up, selected in the same way as the show/hide feature set on the top bar and included in that section.
It would need to include L or R orientation, order and shape of the tool set and the exact choice of what appears.
Although it’s a small graphic, the improvement (or disruption) of workflow is really significant for me as I access these tools so frequently.
