I suggest this over the cycler tool because instead of having to left click for every single cardinal direction, you can take away corners and aspects of blocks for stairs and walls much easier just by looking at them. Similar to the extrude tool we have now but it can both intrude and extrude, making it easier for us to get corner stairs with only 1/4 or make fences unconnect. I would also suggest making unconnect on by default with the tool like wctools extrude.
