Please support UBL instead of ABL

[scyto]

Given all the issues I and many others continue have with first layers could SM please move to using UBL instead of ABL as:

1. it allows the use of sensor
2. it measures many more points
3. it includes tools for manually weaking mesh (test pattern)

Thanks for your consideration.

Does ABL work? Because for me it's displayed as "not working" (Octoprint)
