Well, its just a mild suggestion.
Most of the cases, users do not upload pictures.
However, for a certain forum (e.g., my forum), they post lots of pictures. And it should be more user-friendly to arrange pictures automatically with flanking lines. Or, maybe nodebb could add a switch in the system management panel, then let the administrator to choose automatically arrange pics or not.
I love the dashboard but would LOVE to see more information available, specially around site performance.
Post rates, not just view rates and user rates. Thread rates too.
Stats per day, week, month not just by the hour.
Selectable time periods, not just one day but week, month, year, etc.
Stats about IP addresses or ranges, browsers if possible.
Just more info in general.
