I've been working on an interesting application I want to show off and get some feedback on: Garuda Downloader
It is a user-friendly ISO downloader with a focus on saving bandwidth via delta downloads by utilizing zsync2. It provides an easy UI for downloading the latest (official, not development) live images of all the official editions. On Linux, you can manually select an older ISO file as a "seed" file in order to save bandwidth.
After an ISO file has been downloaded, it provides a button to quickly launch a recommended flashing tool (Etcher on Linux, Rufus on Windows (only because the Rufus executable is absolutely tiny)).
And of course, there is a garuda-downloader-git package in the AUR and in Chaotic-AUR
Let me know what you think, what issues you may have found and what I could improve, thank you!
