The changes that the GNOME development team has brought have not liked many people and it is no secret to anyone that, Canonical and GNOME have had their encounters on several occasions so it would not be strange to anyone if Canonical wants to get rid of that dependency that ties it to GNOME.
The latest versions of File (old Nautilus) have been mutilated with many of the functionalities that made it a fairly complete file manager, so Oliver Grawert, Ubuntu developer, poses on the mailing list Ubuntu-Desktop, that the time has come to use the applications based on QML for the convergence of Unity across all devices.
with the planned switch to unity8 in 14.10 it is most likely that we will also start using the converged QML apps that are developed today.
With all the complaints and unhappyness about Nautilus upstream ripping out things like dual pane and other beloved and helpful features I expect we can do better and I think this is the right time to:
file whishlist bugs
if * you * want to contribute, get in contact with the developers (CCed)
the new core apps are all 100% developed by the community under guidance of the canonical design team.
the code for the filemanager can be found at https://launchpad.net/ubuntu-filemanager-app
it is running on phone and tablets already and has a proper convergence mode adapting to bigger screens.
If the change occurs, it would be for the launch of Unity 8 together with Ubuntu 14.10. At the moment a firm decision has not been made in this regard, but as they say out there “When the river sounds, it is because stones bring".
What is QML?
Much has been said about QML and the use that Canonical is given in Unity and according to Wikipedia is:
Another development just like Mir?
Are Canonical's GNOME Decisions Appropriate? Will this new file manager have a future or can it run the same path as Mir? These and other questions can only be answered with time.
So far the article published in humans, I hope you find it interesting.
