When I distribute my application to a PC that does not have Node.js and start it, the "Manage Palette" is not found on the menu.
When I installed Node.js on that PC, the "Manage Palette" appeared, but I assume that the application is implemented on a PC that does not have Node.js installed.
"palette" in var settings' editorTheme is true.
Electron version is 20.0.0, and Npm version is 8.19.1.
This will be because on the other PC, node-red will not know there to find the npm command. Also, it should tell you in the start up log why there is no palette manager - if you can access it (I dont know how you have your project setup or if you even redirect output to a file or to syslog etc)
