Actually I really like the way the tool in SketchPlus so I just bought it. I had a similar issue in this thread Pick Deepest Group Extension - #10 by napperkt and after a LOT of researching I found a function in SketchPlus that reduced my clicking in deeply nested projects from maybe 10 double clicks to reach to the lowest group to Shift-D + 1 click (I set my shortcut to Shift-D for “Deep Select”. Tried Curics and tried and I use it too but for VERY different things - like picking ALL surfaces of all groups to get the m2 or something like that. But to reach a particular surface fast SketchPlus Deep Select was the only thing I could find.
The other thing to reduce clicking in Sketchup is to REALLY get into shortcuts. I hardly ever need to click on a tool because I have all important commands mapped to shortcuts and I know them without looking at the keyboard. Get’s really messy if I am at a keyboard that I am not familiar with but otherwise works great…
