SUMMARY
Hello KDE-Team,

I'm coming from windows and run now under cachy-os (details below). Formerly on Windows, I used there Q-Dir which offers a quad-directory view. So I was looking for some alternatives and fell over Krusader. It feels already quite the same as using Q-Dir (src: https://www.softwareok.com/?seite=Freeware/Q-Dir), but unfortunately it does not offer a quad-view. 

Moreover, I noticed that each (dual-view) viewer can fade up a folder-tree. However, that takes a lot of place when enablind that for more than one viewer (split/quad-view). Therefore I also wanted to request an option to allow a single folder-tree view for all viewers (active to the viewer in focus), removing redundancy-space.


STEPS TO REPRODUCE
"new" features, so nothing to reproduce

OBSERVED RESULT
N/A

EXPECTED RESULT
1.) Option that allows Quad-View (in quadrands, size adjustale like tiles)
2.) Option to enable only one folder-tree for all individual viewers (acive for the viewer in focus)
