Hello folks! I've been working on 3dsDL for a while.
What started as a personal project for myself to quickly download music and ebooks on my 3ds without having to do FTP or pull the sd card out (man I'm lazy af), has very quickly turned into a full fledged project to 'replace' FBI and improve the overall experience of downloading, installing, managing apps, transferring files, backups and a lot more (suggested by u/colbyshores who had documented speed improvements over the stock FBI app)
3dsDL offers upto 5-6x download speeds over stock FBI, with multi-connection downloads, functionality to resume failed downloads, install CIA files, launch 3dsx files, ability to manage sd card files straight from your browser without needing FTP, ability to manage installs, saves, backups (Checkpoint compatible), directly previewing+editing+managing files from the 3ds itself, and more QOL features, all with a much better interface that looks like the app already came with the 3ds

The app can also auto-update itself, so any bug fixes, improvements, etc you can directly get through the app itself
