I haven't tried it but looking at it makes me feel nostalgic.
Based on the screenshots I've looked at it reminds me of the KDE desktop environment (DE) of old, back in the 3.x series, long before it would become the Plasma desktop environment. Back then, they had an included program, Konqueror, that was not only an exceptionally capable web browser but also a file manager, a remote desktop client, an FTP client and more. I think at that time, most of us were using KDE as it came with the majority of distributions, unlike the nascent Gnome DE. I should just read the wiki page on it but I believe it's quite fast on the most anemic of computers as well.
Thank you both for reminding me of this lovely desktop environment. I'm having a really tough time this morning so it's good to be reminded of the fonder memories.
