The presentation mode is available in full screen only.
I understand why you may need this non-full screen option and I've added this request to our internal tracker so we can review and consider it for the future.
If others would like to see this feature, please let us know (or add your Like/Heart vote above) to help us prioritize this request.
For now if you need to navigate through your links without being in full screen presentation mode, you can use ALT+click on the little red arrow icons.
Thanks for your input.
