Do you experience any issues with it? Seeing as it hasn't been developed further since 2018, while youtube-dl is still being worked on (including new features).
I’ve honestly never had a single issue with it and wasn’t exaggerating when I said I use it nearly every day. I save any/every video I find useful to my NAS because I don’t trust Google not to delete the persons account for some arbitrary reason.
The only “gotcha” is sometimes downloads fail and if you don’t know to check the logs (in the top menu) then that can get confusing for new users, but usually it’s something simple like you need to update the YouTube-dl core (also just done via the menu) or you chose a download format/resolution not supported for that video.
I certainly did. Issues like crashing out of nowhere, silently failing downloads, etc. So I switched to the CLI option even though I'd have strongly preferred to be able to use the GUI. I was excited by the title of the HN post and then disheartened to see a program of the same name (as I assumed it was this buggy one), glad to see it's a different program.
