Hello all. Sorry it took me so long to answer.
Ernie asked in the first answer how the system knows what presentation formats are available. THey are not hardcoded, but it is not transparent either. the data is stored in the database, in a new table called lors_available_presentation_formats, that contains an id, the pretty name of the presentation, and the folder that contains it.
About the index issue, in the presentation format I am currently working on, there will be no index in the same window. There will only be a small frame with buttons. One of these will be the index, which will open in a new window. There will be also buttons for next and previous page. But we are still working on the design.
greetings
Jonatan.
