I added Network and Sound to the other monitors
Network and sound are a couple of the files that aren't numbered by default.
Even if that stops you from adding them in GUI, this is not a limitation in the back end
Duplicate the named files as many times as you need and name the new files with next available number
as an example, this is the new content of my /sound@cinnamon.org
48.json
50.json
52.json
sound@cinnamon.org.json
All files have identical content
You can rename the original file to its corresponding number but you don't have to
gsettings get org.cinnamon enabled-applets
will give you current list
Here are the new entries I had to make
Panel 2 (Right):
Network:
panel2:right:6:network@cinnamon.org:47Sound:
panel2:right:7:sound@cinnamon.org:48
Panel 3 (Right):
Network:
panel3:right:6:network@cinnamon.org:49Sound:
panel3:right:7:sound@cinnamon.org:50
Panel 4 (Right):
Network:
panel4:right:6:network@cinnamon.org:51Sound:
panel4:right:7:sound@cinnamon.org:52
panel(number) is your monitor, in this case I already had network@cinnamon.org.json and sound@cinnamon.org.json on panel1
right or left is self explained but the number after is the position, it need to be vacant and you can move them later in panel edit mode
Mine ended up as this after moving around:
'panel2:right:4:network@cinnamon.org:47', 'panel2:right:5:sound@cinnamon.org:48',
'panel3:right:4:network@cinnamon.org:49', 'panel3:right:5:sound@cinnamon.org:50',
'panel4:right:4:network@cinnamon.org:51', 'panel4:right:5:sound@cinnamon.org:52']
Add the new info right before the ending bracket. It is all in apostrophes and on one line separated by "comma space"
Use
gsettings get org.cinnamon enabled-applets
To export current list and use
gsettings set org.cinnamon enabled-applets "['one panel', 'after another', 'all in one line']"
To save the new list.
Include the quotation marks (")
