The tabs and address bar on Explorer seem to actually be a copy of the default behavior of Dolphin.

If you are going to copy someone, copy from the best, I guess. But Microsoft managed fill their top-space¹ and not let enough space for the address to be properly displayed, so they need to hide information all the time.

The tabs on PowerShell are actually not a copy of Konsole. I guess that's why I always get annoyed by them on Windows, but not on Linux.

1 - There's actual less stuff than on KDE, if you don't count empty space.

Oh man. the complete lack of definition or contrast from window to window is terrible. Which window are you clicking on? Nobody knows. It's especially painful when you have like three or four nested RDP sessions going on.
