Create content with reload? Perhaps not the html files, but let you drag and drop them into a lesson structure. I made this little test package
http://www.rzuser.uni-heidelberg.de/~x28/reload/zip-datei.zip with the following simple procedure:
File > New > IMS 1.1.3 Content Package
File > Import Resources
Rightclick on Organizations > Add Organization
(dragging Lessons and Intros/Contents/Summaries and dropping them onto the blue Icons)
(see screenshot http://www.rzuser.uni-heidelberg.de/~x28/reload/reload-screenshot1.jpg )
and see how a primitive sequencer could look like by using their previewer:
View > Preview Content Page
