The well-formedness check panel has been improved in several ways to make it easier to work through model issues:

• Severity-first ordering: rules are now sorted with errors at the top, followed by warnings, hints, and passing rules. Previously the order was arbitrary (by internal rule number), so critical errors could appear anywhere in the list.
• Four severity filter buttons: the single 'show only violations' toggle has been replaced by four independent toggle buttons — Errors, Warnings, Hints, and OK. Each can be switched on or off independently, so you can for example show only errors and warnings while hiding hints and passing rules, or show everything at once.
• Violation count always visible: the number of violations per rule (e.g. '(12)') is now shown on every rule row, including when the rule is expanded. Previously the count only appeared when the rule was collapsed.
• Model quality score in the status bar: the overall model quality percentage is now displayed in the main status bar at all times after a check has been run. The score is color-coded (red through orange and yellow to green). Clicking the score immediately re-runs the check.
