alt Hacker NewsThe 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.
With Dolphin you don't get a tab bar until you use multiple tabs. Like OP I never saw the point of the feature though - directories aren't like webpages where I might want to open tabs to read later so anything I open should just be a new window that gets its own space.
