For the launcher framework this is out of scope since the GUI framework can't handle that, use the --help command to obtain all parameters and then setup the server from the command line. If you need help with a particular configuration we can assist in creating a config file.

You can also use --exportconfig to generate these configuration files from the full list of options which saves typing the next time since you can then do --config with the location of where you saved it.

The web ui has already had extensive testing with nvda and received praise from other nvda users to how good that works. If we accidentally reduced compatibility we'd have to know where.
