Some random suggestions:
add categories to the templates
for example if I want to test some new filmanagers or terminals, it would be nice if xbps-query could display a list of forexample gtk,filemanagers.
This could also be used in the installations medias installation script, to for example display available boot managers, on a net-install.
set the forum default to “Categories”, you can still see the latest post on the right side still.
choose some less bright background for the forum, it kinda hurts the eyes.
