Anyway, here is one youtuber that I've subscribed into making a decent review on this tool:
disclaimer: 3 year old video, the tool may become more mature by now.
disclaimer #2: As a Fedora KDE user, I haven't had the need for this tool anyway - I've a pre set dnf update command and a bash script if I also want to include flatpaks to update if I'd decide to run xfce or mint spins of Fedora instead - because that is a well tested solution that have worked for years for me.
