I think you’re referring to the “file picker” window. i think qBittorrent is using Dolphin as the file picker and as everyone else commented already you can get the same behavior if you use the “Details” view. Go the settings on Dolphin and tick the Expandable option

Alternatively, you can add the Folder panel (F7) and have the same functionality while having a “Compact” or “Icons” for the files

It seems that there are unofficial ports. OP could test it out before.

I think for OP it would be better off with a Framework laptop. It makes more sense in the long run.
Linux on ARM is great for SBC servers but not so good on the graphics stack. As @Vittelius@feddit.org pointed out Snapdragon SOCs are still lackluster. I’m sure Framework will have ARM in their lineup in the future (there’s already a RISC-V mainboard) while support for these CPUs keep improving.
On the other hand, i recently bought a 6 years old lenovo, installed Fedora KDE and it all just works, more importantly for me power management is no longer an issue. It will never be on the level of the newest Apple silicon though.
