The python3-opensnitch-ui package has "opensnitch" in suggests. Because this
package also contains the main GUI along with desktop files and AppStream
metainfo file, it (correctly) shows in package management GUIs as the main
package. Installing this package without the "opensnitch" one being
installed results in non-working firewall GUI and confused users.

Please, consider changing the "opensnitch" suggests to recommends.
