Glad there's a bed leveling wizard but I hate it at the same time. Right now, it runs through the points script twice then goes "Yey you did it" without verifying that you actually achieved a level bed. Additionally, you have to use a Mouse to advance the script.
1) Ask is your bed level yes/no - if yes then close the wizard. If no, then rerun it
2) If possible, add a feature where if I manually move the extruder to a location, then hit a button and the machine homes the extruder and figures out where you were and use this to set the leveling point. And do this for all points instead of having to type them in. Maybe you can get a "here's how accurate your leveling is based on X points across XY surface" or something like that.
3) Advance the script by hitting the space bar. If you add nothing else, please add this one!
4) Add a visual marker on the build plate showing where you're measuring from based on the script. It's a creature comfort but it would be nice.
