Hello, this is Megalon from the Beat Saber Modding Group Discord.
I've recently learned that the mapping community within our Discord server has several complaints about the beatsaver-viewer, and have started building their own tool as a replacement.
However, most of the issues don't appear to be listed here in the issues for this repo, so I've posted them below.
1. No audio plays and no notes appear when specifying a zip file
2. Skips notes if too many appear in the song
3. VR starts randomly
4. No mapping extensions support, causes walls to stretch across the entire screen
5. NJS is not calculated properly, makes high NPS maps unreadable
6. Can’t view any game modes besides standard
7. Can’t see custom difficulty labels
8. Walls are buggy in general
