The future Ubuntu 17.10 is still unknown. Although there are developments, the truth is that the functions of Gnome are unknown. Ubuntu's enhancements to Gnome Shell are unknown and puzzling.
In any case, based on current developments, it appears that Ubuntu 17.10 will have a quite vitaminized Gnome, that is, with quite a few extensions and add-ons that can make the desktop look good but can also make the desktop consume more resources than normal.The team Ubuntu doesn't want to lose all Unity functionality. This means that certain Gnome Shell extensions are currently being worked on to incorporate into the Ubuntu version. We have already known extensions such as Dash to Dock, but other extensions such as Launcher Backlight are also being worked on, which will be incorporated in the Ubuntu version of Gnome.
Ubuntu 17.10 will have a supervitaminated Gnome
Shuttleworth claimed that I would use as clean a version of Gnome as possible and improve it as much as possible. It is something that excites Gnome fans, but it is true that adding and customizing the desktop with extensions is something that many distributions do and it is also something that does not convince users of these distributions. Not to mention that they are usually heavier desktops than the clean version, so not all computers are compatible with this desktop.
But as we say, development is still unknown and we only know about Ubuntu's participation in the development of certain extensions, we do not know if they will really be in the final version or not. In any case, it seems that nobody wants to lose Unity and it would be nice to save current settings that we have in case in a few years Ubuntu will reuse Unity again. Total, it has already happened with Gnome, it could also happen with Unity Do not you think?
If the one we have, unity, works, why change it? Those of gnu / linux are like this: If something works, let's not develop it and leave it, we have to change it!
What is that? Frankenstein's desk?
For me Unity should always have been developed on Gnome Shell instead of Compiz.
The attraction of Ubuntu is its additions and if they do it through extensions, those who do not like it can deactivate it with a simple click. And if not, there are no alternatives!
In short: "We are going to revive Unity through Gnome extensions instead of our own desktop." Sounds good to me, but let's see how they weather the consumption of RAM, already excessive in Gnome.
The advantage they will have is that through extensions they will only have to update these instead of the desktop; for what Unity, its problem in the end, was a giant with feet of clay, with multiple versions in its packages.
