As far as I can tell from a quick search it seems like it’s closed source.
sigh The search continues, why can’t I just have folders in the app drawer in lawnchair :(
Edit: according to a closed issue on the lawnchair GitHub, app drawer folders have already been in nightly builds for ~6 months, so hopefully it’s in the next beta release.
I use refind also, there should be a setting somewhere to let refind scan entries from other EFI partitions. I have that setup and just created a second EFI partition for my Linux setup, so that Windows has no idea Linux even exists. I even have everything running off of the same drive (my laptop only has one nvme slot) and I haven’t had any issues.
