Dear Maintainer,

The Cinnamon menu system doesn't seem to support the Science category,
with the consequence that when a package ships a .desktop file with
that category, the entry shows up in the "Other" submenu. The spec at
https://specifications.freedesktop.org/menu-spec/latest/apa.html seems
to indicate that the Science category is a "must support", and I was
quite surprised not to find it implemented in Cinnamon.

Thanks,
Roland.

This is now fixed upstream for next major version:
https://github.com/linuxmint/cinnamon/commit/bc9b012694eb81db7f154754557caf3ca431491f

This was fixed upstream by commit bc9b012 ("Add a Science category to the
menu. (#12215)", 2024-05-31), which adds the cinnamon-science.directory
entry, the Science menu section in /etc/xdg/menus/cinnamon-applications.menu
and excludes the Science category from the Education menu.

The fix is in upstream Cinnamon since 6.2.0, and in Debian since cinnamon
6.2.9-1. I verified it on the binary packages currently in the archive:
both cinnamon-common 6.4.10-2 (trixie) and 6.6.9-1 (unstable) ship
/usr/share/desktop-directories/cinnamon-science.directory and the
corresponding <Menu><Name>Science</Name> section, so applications whose
.desktop file declares Categories=Science are now listed in their own
Science submenu instead of falling back to "Other".

Bookworm still has 5.6.8-1 and will keep the old behaviour.

Thanks for the report.
