Hmm, that seems a little silly needing to make auto group creation as a suggestion. Groups are integral to my Bigfix core functionality and if removed/deprecated, I would probably move away from Bigfix.
My current group count for a 14k+ endpoint environment is 1131. With cleaning I could probably prune that to 700 or so, but most of my sites/permissions/patch groups/reporting etc are based on auto grouping.
Whether that is best practice or not, it is what it is.
I think my point is that if the Bigfix devs want us legacy folks to move off console and to WebUI, we need the core functionality for administration tasks migrated also. Group support should have been one of the initial core abilities in WebUI, not a suggestion.
