I prefer Synaptic Package Manager for a GUI package manager.
sudo apt install synaptic
Generally, I do most installations (by far) from the terminal. Synaptic is handy when I need it mostly for removals.
The Gnome-Software app follows the same pattern as all other Gnome-apps: Minimalist and Broken. Gnome is much like Microsoft, treating the user as incapable and unintelligent and limits user control and access.
The only reason I keep gnome-software installed on this system is to assist users on this forum with troubleshooting. Otherwise, I would have wiped it off the computer by now with a thermonuclear warhead.
One handy way of being able to remove .deb files that are independently installed by the user is: When you install a .deb package, create a new folder in your Downloads directory and label it something like: installed
Once you install the .deb package, move that .deb file into that installed folder.
Then when you wish to remove that package, double click that same .deb package you installed with to pull up the manager that will offer to remove it.
The above method can take up some extra space, though.
