Starting to test it now…
About the Design Rules >> Constraints. I like the icons, very intuitive.
The zone fill option should be a option box (as Design Rules >> Violation Severity), not a check box.
I would like some import/export (JSON or INF format for example) of the Design Rules >> Constraints. This will be nice to easy define the manufacture specifications (also the limitation of the university drill machine).
It could also include the a checkbox for “Allow vias under components” (default ON with a ballon tip: it may make DRC lower when OFF). This check for vias inside the parts contours (interesting for home and university hand-made PCBs).
I have linked the Gitlab reports in this comment revision.
