DSP and Menu questions Options

[emilles]

I am currently working on a DSP component for FB2K. The DSP interface seems to be working fine. Now I am trying to add some convenience menus or menu items so that the user does not need to go to Preferences > Playback > DSP Manager, etc. (That's a lot of steps.) When holding Shift, I see a couple nice menu items for getting directly to the DSP prefs and changing the Output device.

1) Is it possible to add a menu item to the Playback menu > DSP settings' submenu? Seemingly that would be the place for all DSPs to attach their extras. If not, should "DSP settings" be a command menu item labeled "DSP Manager" instead that carrys out the command of the submenu's Preferences item?

2) Is it possible to add to the Playback > Device submenu? My component will be sending audio to one or more remote devices. The Device submenu seems like a decent place to add the list of remote devices as a group and allow selection / deselection.

3) I'm trying to make a menu group that is populated dynamically by the remote devices found on the local network. It appears that mainmenu_commands is only queried once when a menu is opened for its length. So if a device appeared or disappeared, I seemingly could not update the menu group live; I would need to wait until the menu was reopened. Does the mainmenu_commands_v2 add this capability? I can't seem to make much sense of the difference or how to create mainmenu_node instances correctly.

This menu contains all "DSP chain presets".
