view the music sheet in the Horizontal sense

[kaelyavel]

Music Box Fun is wonderful. Adding the Horizontal rotation while making music sheets would add more flexibility.

For the Horizontal feature: most musical composition or presentation things (software or not) that I'm familiar with are written left-to-right instead of top-to-bottom, so it definitely takes more mental power for me to adapt to the vertical format.

Here's a few more thoughts I had on horizontal vs vertical:

• It would be nice if this switch could be entirely CSS powered (though I'm not sure how realistic that is, with the intersection observer, and "back to top" code)
• I think the easiest way to accommodate the sidebars in a horizontal arrangement would be to hide them behind menu icons like we do at mobile breakpoints. This would also make it easier for the horizontal arrangement to work on mobile.
