Plugin not appearing in Menu
I've run into this several times now. I create a plugin (might be as simple as duplicating and renaming a working one) that shows in the plugin manager, but even after reloading plugins or restarting MuseScore, it doesn't show in the plugin menu. (I think) the workaround is to quit MuseScore, take the plugin completely out of the plugin folder, restart MuseScore without the plugin that isn't showing, drag the plugin back into the plugin folder and use the plugin manager to reload plugins.
I haven't been able to figure out why some of my new plugins behave like this.
