The "browse source code" link on this page https://www.crumplab.com/midiblender/ does not go to https://github.com/CrumpLab/midiblender/tree/main/, which I assume it should.
I can't figure out what's going here.
There a few closed issues about this on pkgdown, I can't tell what's wrong on my side yet.
