Extensions add immense flexibility to the GNOME 3 desktop environment. They give users the advantage of customizing their desktop while adding ease and efficiency to their workflow. The Fedora Magazine has already covered some great desktop extensions such as EasyScreenCast, gTile, and OpenWeather. This article continues that coverage by focusing on extensions tailored for developers.

The Docker Integration extension is a must for developers using Docker for their apps. The status menu provides a list of Docker containers with the option to start, stop, pause and even remove them. The list updates automatically as new containers are added to the system.
After installing this extension, Fedora users may get the message: “Error occurred when fetching containers.” This is because Docker commands require sudo or root permissions by default. To configure your user account to run Docker, refer to the Docker Installation page on the Fedora Developer Portal.
You can find more information on the extension’s website.

Developers using the Hotel process manager for their web apps should explore the Hotel Manager extension. It displays a list of web apps added to Hotel, and gives users the ability to start, stop and restart those apps. Furthermore, the computers icon to the right gives quick access to open, or view, that web app. The extension can also start, stop, or restart the Hotel daemon.
As of the publication of this article, Hotel Manager version 4 for GNOME 3.26 does not list the web apps in the extension’s drop-down menu. Version 4 also gives errors when installing on Fedora 28 (GNOME 3.28). However, version 3 works with Fedora 27 and Fedora 28.
