## Description

Flatline is a useful Chrome extension that streamlines the installation of Flatpak applications via popular software portals like Flathub, apps.gnome.org, and appcenter.elementary.io. By integrating with these platforms using AppStream technology, Flatline allows users to open GNOME Software or any Flatpak-compatible software center directly to an app's detail page with a simple click. This tool requires Flatpak, a Flatpak repository such as Flathub, and GNOME Software or a similar flatpak-supporting center installed on your system.

With Flatline, users enjoy a seamless experience managing Flatpak apps without manual searches or commands, enhancing ease of installation and app management for Linux users who prefer graphical interfaces.
