If the Smart Lighting SmartApp days are numbered and my entire list of Smart Lighting Routines are combined with all of my Automations, that would make for a very long list which would be horrible to navigate and find anything on. In that case, I sure hope they bring some cosmetic changes to the Automation list if (or when) that happens because I’d at least need containers/subfolders/rooms/groups, etc (whatever you want to call them) to correlate/separate the long list of Automations.
BTW, SmartThings support once told me that their is a 250 Automation Behavior limit. And I’ve read throughout this message board that their is an Automation limit of 200 apparently. So if they merge the Smart Lighting Routines to Automations, then I’d imagine any Automations limits would need to change.
