That UI may make some sense on mobile where a finger, which is bigger than a mouse pointer, must operate bigger controls comfortably; but on desktop? Nope, old interfaces win over "modern" ones any day. For example, down that page there's a Transmission remote GUI screenshot (I use it as Transmission here is a daemon on my headless XigmaNAS server).

What would be wrong with it or anything similar? Every information is just there, no need to swipe left and right to read information that has been either hidden elsewhere or, worse, taken away. The same applies to many "old" clients such as QBittorrent and others.

I understand that design is important, but it should never ever win over functionality.
