Grouping sounds like a great idea to me. I would want the ability to collapse/expand rather than organize by color or icon. I want to reduce visual clutter and make it easier to find a rule quickly.
I could also see some sort of filtering capability. For example, I know my rule involves a particular device… show rules that involve this device.
One question I have (slightly off topic). Most of my rules are setup as automations in ST. Is there a good reason to convert my automations over to SharpTools rules? I haven’t actually looked into whether my automations run on my hub or not, but I figured I had the greatest chance of running them locally if I used automations.
