Many thanks for helping out while my brain recovered from the insane work hours this week, Ian! You're the best!
Poor Ian has been chained to his desk in the den for so long that he's a touch behind on the specifics. I'll try to ensure he gets out more.
We absolutely plan to bring the 5ESRD to Hero Lab Online and we are also working toward making the authoring kit available in the future. We aren't there yet, but it is a priority!
Additionally, we have nothing against WoTC, and are actively pursuing an official 5E license. While nothing is set in stone, I have hope that the future of HLO will one day include licensed 5E content.
