Signed, Omacom's PDF signing app, takes Xournal++'s place in the base
install and the preinstall set, so Remove and Install Preinstalls cover
it too. A migration installs it on existing machines, unless their owner
has removed the preinstalls; Xournal++ stays on machines that already
have it. The Filling out PDFs chapter now walks through Signed, the GUIs
chapter introduces it, the setup tip points to it, and the unused
Xournal++ config is gone.

Add "Coming From Mac or Windows" as chapter 3: a translation layer for
Cmd/Win instincts rather than a feature tour.
Fill the remaining coverage gaps: fcitx5 input methods, laptop speaker
tuning, touchpad haptics, crash capture in the toggle table, the
installable font list, and the ChatGPT Desktop and Grok Bot entries.
Correct claims that drifted from the source: the network and bluetooth
bar icons no longer launch nmtui/bluetoothctl, monitor scaling steps
rather than cycles, and the display widget's scroll steps brightness.
