The following idea might not be as valuable as some of @SeanAdams posts, but it would save this user precious fractions of time. When I leave the canvas with my mouse (point A) to go up to the pallet I select and drag the tool down to the canvas. Sometimes I do right-click and go through the menus to add the next tool, but generally I go through that labor only when I'm inserting in-stream the tool. So here is my idea:
Double-Click your NEXT tool and it "Alteryx-ly" appears on your canvas in proximity to the hi-lighted (last) tool. Better yet, connect it! Now I can move from the pallet to the configuration panel directly without having to move my mouse down to the canvas and then over to the configuration panel.
Hopefully, my friend @Hollingsworth will find this time-saving idea worthy of a star. Speed demons like @NicoleJohnson and @BenMoss might not need this turbo boost, but at my age it is worth the ask.
