1 "report features only" means that the profile's reports can be customized through the Config section of the GUI. This is possible in all tiers except Lite, where the Config section is limited and does not include a report editor. "complete via Salang" means that the full Salang source code of the web interface is open to be modified (subject to licensing restrictions - available on request).
