I know you’re really busy getting 7.3 out, but I hope you will reconsider the configurable structure of this component, at least long-term. Every active alarm screen I’ve worked on in the last 28 years had similar attributes, usually called out in the client’s requirement spec that must be met:
Alarms/Alerts #1 in sort order is High Severity/Unacknowledged/Active
Alarms/Alerts #2 in sort order is High Severity/Acknowledged/Active
Down through the other severities.
Each alert combination would have a configurable foreground/background/blink color combination for the sites spec requirements.
Maybe offer alternative flavors of this component so as not to interfere with the current one?
I will roll my own for this project as you suggested, but I know that under some bidding scenarios I could easily lose Ignition projects by not being able to natively meet alert handling specs.
