In PRESENTA the first-citizen view is the grid layout rather that the common sidebar+canvas provided by all the other popular tools such as Powerpoint, Keynote and Google Presentation.
There's a reason for that:
having a clear overview of the whole is much more meaningful than a partial representation.
A presentation document is a sequence of concepts and each slide serves a specific purpose in a given context.
The bird-eye view is also well supported by the way PRESENTA display texts (less and bigger) giving the possibility to constantly reviewing the whole flow of the document, reading chuncks of text here and there.
We believe the PRESENTA default slides view is a better tool when building a presentation than a single slide focussed view of other popular tools.
We know, it's something the others don't do, but there's a very dangerous saying, you know? "we always do it that way".
