Kate should preserve Unix file mode on "Save As..." operation. That is the copy should have the same permissions as the original file. Reproducible: Always
Confirmed it loses permissions. Arch Linux 64-bit Kate 16.04.2 KDE Frameworks 5.22.0 Qt 5.6.1 xcb wm
Dear user, this wish list item is now closed, as it wasn't touched in the last year and no contributor stepped up to implement it. The Kate/KTextEditor team is small and we can just try to keep up with fixing bugs. Therefore wishes that show no activity for a years or more will be closed from now on to keep at least a bit overview about 'current' wishs of the users. If you want your feature to be implemented, please step up to provide some patch for it. If you think it is really needed, you can reopen your request, but keep in mind, if no new good arguments are made and no people get attracted to help out to implement it, it will expire in a year again. We have a nice website https://kate-editor.org that provides all the information needed to contribute, please make use of it. Patches can be handed in via https://phabricator.kde.org/differential/ Greetings Christoph Cullmann
I don't see that somebody wants to implement that nor do I really see if that should be the default behavior.
