Recently we (Neptune) held a getting started webinar on how to create a fully functional Sales Order Search application based on UI5 using the Neptune Application Designer.
The coding (minus the backend ABAP coding which was only walked through) took our CEO Ole-André Haugen 40 minutes to complete 
The video shows a lot of tips and tricks that will make your Neptune programming faster. Therefore, even if you are an experienced user of our tool, I think it might be worth to view.
Also at the end of the session, we showed some of the new cool features we released in SP3.
That includes features such as a new AppCache configuration, upgrade of the Select component using a dictionary table or domain value range without any coding and the introduction of the newest version of OpenUI5.
Well here is the video, and I will shortly post the second video in these series that covers the superb Neptune offline solution.
