When you use the Settings - Syntax Specific menu item on an opened file say e.g. a Plain Text file, you can edit the Plain text.sublime-settings preferences file.
If you use the Settings - Syntax Specific on a .sublime-settings file you edit a JSON.sublime-settings file.
I am not totally agree with this. It is true that .sublime-settings files are in “JSON like” format, however they are not true JSON (comments are permitted, for one thing).
In my opinion, the specific preferences file for .sublime-settings files should be something like:
Sublime Settings.sublime-settings
(or without space, or with dash … it’s not relevant). Not JSON.sublime-settings.
It may seems a bit recursive but it has sense for me.
