@hermeticvm@convo.casa What are the main issues you have with them? I found Dolphin and Nautilus pretty much got the job done when I used them. Portfolio hasn't worked as well for me since it's more for mobile. Right now my XDG desktop portals and KDE themes are kinda fucked since I'm building a wayland desktop environment from scratch, but with the standard GNOME/Plasma setups it seemed fine.
Then again I am usually in the command line anyway >:P
