Void Linux and Clear Linux have a Packages/Software section right on their respective homepages .
Arch Linux has a Packages widget right in the main website , If you go to Source Mage's Website , their Packages section ; affectionately called the "Grimoire" is only a few clicks away .
If you go to Mageia's , openSUSE's or Debian's website , there is no Packages section right in the main website , but if you search for them online , you will find it - it's madb.mageia.org , software.opensuse.org and packages.debian.org respectively . I still think the link should have been a part of the main website .
Solus and Fedora are undoubtedly mainstream quality Operating Systems , if they just did this ; there's literally nothing else to complain about .
