The current options in GUI to start the HTTP server only handle the port option (the equivalent of the command-line option --port).
There is no option to set allow origin (the equivalent of the command-line --allow-origin)
Because of this the GUI cannot currently be used to start a server to be used with, e.g., the current Javascript webextension.
The only way to currently set this option is to start the server from the command-line.
So if a user (like me) wants to have both the server and the GUI, the user needs to a start two separate java processes.
Would it be possible to add support for setting origin from the GUI ?
