I've used Konqueror as a file manager forever; it's more configurable by far than Dolphin, and it always opens to my preferred profile. At least it did until I upgraded to F26. Now it opens to a 'malformed url' page. I can set it up as before, but the 'save profile' (web browsing, file management, etc) option is no longer there.
I can save my setup as a session, but there is also no way to make it a default session, so it still opens to the malformed url page. Once I go into the menu and click the session it opens a whole new instance of Konqueror, so I have to close the malformed instance.
Also there is no option for single-click anymore, and even though I have single-click chosen in KDE settings, I still have to double-click in Konqueror. AND, it only shows a few folder icons Documents, Downloads, and on the / side it only shows /tmp. Everything else is just a name with no icon. Changing icon preference from oxygen to breeze, mist or adwaita makes no difference so apparently it can no longer see icons.
I'm assuming all the 'forgotten' options were intended to make things more streamlined, but they streamlined my favorite file manager to pieces.
I live in my own little world, but it's OK, they know me here.
