Request for OpenRefine

I created a prototype for the Flatpak app.
Since I’m a Java programmer, I inspected a little the launcher code. I don’t think it’s a good idea to run the browser along with the server.
Anyway it starts, but I didn’t find a way to stop the server once finished.
You can tell the development team to start from this example.
I didn’t test the app at all.
I’ll remove the personal repo one day or another.
