Collabora Online is a collaborative online office suite based on LibreOffice technology. This is also the source for the Collabora Office apps for iOS and Android.
I understood that on desktop apps like in LibreOffice Impress you have the sidebar with the previews and in the main section the actual slide.
On mobile it's way easier to slide through a presentation (like you do in writer where you slide from one page to the next one) than you click one the previews. I understood that it's easier for editing one page after another and you see only one page, but on mobile you ordinary view content and for viewing it's way easier to scroll through the impress slide like you do at writer text files.
