From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I installed flatseal but I never understand what is essential and what is not.
It is mostly trial and error. I use it mostly to set envvars.
As an example, I add the ~/.themes folder and the GTK_THEME to allow some apps to get the themes I downloaded.
Oh, so flatpaks cannot automatically get system themes?
If it is trial and error, is it really useful for a normal user?
System themes, probably most of them work. But most of them don't bother watching the user themes or icons folder.
I don't think Flatseal is that useful for the majority of users, no. But it is a good tool to have in mind when the need arises.
Why do you think it is not useful?
I replaced Firefox system package with Flatpak because I think browser is the most used and vulnerable thing in my system. And the size seemed reasonable.
I did not replace Thunderbird because its size is almost 10 times.
The person you're replying to is talking about the permissions manager flatseal, not flatpaks
Oops. I got confused
