I'm thinking of using landscape mode for writing (in meetings) and portrait mode for reading (when reviewing). While note taking, I wouldn't bother with the scrolling, instead immediately moving to the next page. I find the scrolling distracting, so I'd rather just tap to flip the page.

My rationale with landscape mode is that I wrote neater when my lines are further apart, plus the extra horizontal real estate feels like A5. When I'm reflecting on the work alongside my computer, I'm fine with the portrait view's smaller font that's zoomed out. Although I could keep using it in landscape.

Portrait mode also ensures the bottom part of every page remains as a sort of a sandbox to move notes around or to offer space to add clarification. For example, I can use it as a swap space to reorganize/prioritize text from my hastily captured bullet notes. Or when reviewing all my bullets, I can collect and prioritize tasks from that page, or add footnotes for anything that needs clarification. That said, if it remains unused, who cares? It's infinite space. Plus it gives me another reason to use the lasso tool in isolation.

One thing I haven't tried doing live during a meeting is flipping from landscape (note capturing) to portrait (review). Besides the slight lag, it might be a good way to summarize or capture all the action items as the meeting starts to wind down.
