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?
