For bug reporting and enhancement request I am always using:
https://www.libreoffice.org/get-help/bug/
which gives me a nice structure and helps me enclose all information needed to be reported and, at the end, provides me a link to the related bug on the bugzilla homepage
I am also seeing often hints to go to
https://bugs.freedesktop.org/
What is are the reasons for the recommendation to directly to the bugzilla homepage?
