Custom page size does not allow portrait mode where width > height.
If I have a score with a few lines, I would like to shrink the page to hide the trailing space at the bottom of the page when displayed but print normally, that is at the top of a portrait mode. If I try to change, say a letter size, so that the height is less than the width, the software automatically switches to a landscape mode which may not be what I want. A workaround is to manually set the orientation back to the portrait mode when printing the score. This, obviously, is an inconvenience.
Suggestion: decouple the selection of Landscape, Portrait modes from page height and width for custom page sizes.
An option to remove trailing space from a page (or the last page) when the score is played in an iFrame will also be great.
