about extension manager

In the next article we are going to take a look at the Extension Manager. This is an unofficial app that will allow users to search for and install GNOME Shell extensions from the desktop. All of them without the need to use the web browser, as usual. The app is built on GTK4 and libadwaita and is available to install from Flathub.

Today, in addition to allowing users to search for and install extensions that are also found on extensions.gnome.org, this tool also It will give us the possibility to enable or disable extensions, show a list of installed extensions, access their configuration or uninstall them. The app is still quite new, it had its first release a short time ago, although it has already received an update in which its creator added some of the things that users have asked for.

Among the things that have been included, we can find a global on/off switch (just like the official tool) and a clear separation of user-installed extensions and system-installed extensions (alphabetically arranged).
