During the Outsystems Usergroup at Nextstep 2019 in Amsterdam someone asked why the technical sessions weren't very technical or in depth. The reason for this is that there's a wide range of experience and expertise among the attendees of Outsystems and the technical sessions are open to all of them. This makes sense, but the short 20 minute sessions are hamstrung by having to go over basic stuff sometimes.
Perhaps for the next NextStep you could implement some sort of complexity indicator for the technical sessions. For instance, associate and professional level technical sessions. This would allow the professional sessions to skip over the basics of development and get more technical or in depth on a specific subject.
