Option to exclude vertical slides during exports
Often I use vertical slides as "extra slides", i.e. slides that I won't show during my presentation but which contain useful information and hence might be brought up during the following Q/A session.
This approach is useful (as opposed to having the extra slides at the end of the presentation) not only for the Q/A session but especially for interested readers who view my slides later on. By browsing the vertical slides they can easily obtain additional, more detailed information about each main slide, for which there is no time during the actual presentation.
And that is the reason why I would appreciate the option to exclude the vertical slides for an export to PDF or PPTX. Often these formats are required when presenting on a larger conference but I don't want my vertical extra slides included here.
This feature seems easy to implement and it would be very helpful in my opinion.
